+# MalioDateWeek — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Composant `<MalioDateWeek>` (sélection d'une semaine ISO en un clic, hover de semaine), réutilisant le shell + le rendu pilule de `DateRange`.
+
+**Architecture:** Une semaine sélectionnée est une plage lundi→dimanche : `DateWeek` calcule ces bornes et les passe à `MonthGrid` (rendu pilule réutilisé). Ajout de 2 props additives à `MonthGrid` (n° de semaine cliquable + repère) et d'un module pur `dateWeek.ts`.
+
+**Tech Stack:** Nuxt 4 layer, Vue 3 `<script setup lang="ts">`, TypeScript strict, Tailwind (`m-*`), `@iconify/vue`, Vitest + `@vue/test-utils` (jsdom).
+
+**Référence spec :** `docs/superpowers/specs/2026-05-20-dateweek-design.md`
+
+---
+
+## Conventions
+
+- Tests ciblés : `npx vitest run <chemin>` ; commits avec `--no-verify` en cas de hook flaky (suite complète lancée par le hook).
+- `data-test` réutilisés (`date-input`, `popover`, `header-*`, `day`+`data-iso`, `clear`, `calendar-icon`, `month`, `week-number`).
+- Nouveaux attributs sur la cellule n° de semaine : `data-week-start` (lundi de la ligne), `data-marked` (`"true"`/`"false"`).
+- Ordre : 1) `dateWeek.ts` → 2) extension `MonthGrid` → 3) `DateWeek.vue` + tests → 4) story + playground.

+## Task 2 : Ajouts additifs à `MonthGrid.vue`
+
+**Files:**
+- Modify: `app/components/malio/date/internal/MonthGrid.vue`
+
+Couvert par `DateWeek.test.ts` (Task 3) ; non-régression par `Date.test.ts` / `DateRange.test.ts`.
+
+- [ ] **Step 1 : Remplacer la cellule n° de semaine** par un élément polymorphe interactif
+
+Dans le template, remplacer le bloc actuel :
+
+```vue
+        <div
+          data-test="week-number"
+          class="mr-[12px] flex h-[45px] w-[35px] shrink-0 items-center justify-center bg-m-primary-light p-[10px] text-sm"
+          :class="[
+            week.days.some(d => d.isToday) ? 'text-black' : 'text-black/60',
+            wIndex === 0 ? 'rounded-t-md' : '',
+            wIndex === weeks.length - 1 ? 'rounded-b-md' : '',
+          ]"
+        >
+          {{ week.weekNumber }}
+        </div>
+```
+
+par :
+
+```vue
+        <component
+          :is="interactiveWeekNumber ? 'button' : 'div'"
+          data-test="week-number"
+          :data-week-start="week.days[0].isoDate"
+          :data-marked="markedWeekStart === week.days[0].isoDate"
+          :type="interactiveWeekNumber ? 'button' : undefined"
+          :disabled="interactiveWeekNumber ? !weekSelectable(week) : undefined"
+          class="mr-[12px] flex h-[45px] w-[35px] shrink-0 items-center justify-center p-[10px] text-sm"
+          :class="[
+            weekNumberClass(week),
+            wIndex === 0 ? 'rounded-t-md' : '',
+            wIndex === weeks.length - 1 ? 'rounded-b-md' : '',
+          ]"
+          @click="onWeekNumberClick(week)"
+          @mouseenter="onWeekNumberHover(week)"
+        >
+          {{ week.weekNumber }}
+        </component>
+```
+
+- [ ] **Step 2 : Ajouter les props et la logique** (script)
+
+Modifier les `defineProps`/`withDefaults` pour ajouter `interactiveWeekNumber` et `markedWeekStart`, importer `WeekRow`, et ajouter les helpers. Remplacer le bloc props :
+
+```ts
+const props = withDefaults(
+  defineProps<{
+    month: number
+    year: number
+    selectedDate?: string | null
+    rangeStart?: string | null
+    rangeEnd?: string | null
+    previewDate?: string | null
+    interactiveWeekNumber?: boolean
+    markedWeekStart?: string | null
+    min?: string
+    max?: string
+  }>(),
+  {
+    selectedDate: null,
+    rangeStart: undefined,
+    rangeEnd: undefined,
+    previewDate: undefined,
+    interactiveWeekNumber: false,
+    markedWeekStart: null,
+    min: undefined,
+    max: undefined,
+  },
+)
+```
+
+Mettre à jour l'import du composable pour récupérer `WeekRow` :
+
+```ts
+import {useMonthMatrix, type DayCell, type WeekRow} from '../composables/useMonthMatrix'
+```
+
+Ajouter, après `const inRange = ...` :
+
+```ts
+const weekSelectable = (week: WeekRow) => week.days.some(d => inRange(d.isoDate))
+
+const weekNumberClass = (week: WeekRow) => {
+  if (props.markedWeekStart === week.days[0].isoDate) return 'bg-m-primary text-white'
+  const parts = ['bg-m-primary-light']
+  parts.push(week.days.some(d => d.isToday) ? 'text-black' : 'text-black/60')
+  if (props.interactiveWeekNumber && weekSelectable(week)) parts.push('cursor-pointer')
+  return parts.join(' ')
+}
+
+const onWeekNumberClick = (week: WeekRow) => {
+  if (!props.interactiveWeekNumber || !weekSelectable(week)) return
+  emit('select', week.days[0].isoDate)
+}
+
+const onWeekNumberHover = (week: WeekRow) => {
+  if (!props.interactiveWeekNumber || !weekSelectable(week)) return
+  emit('hover', week.days[0].isoDate)
+}
+```
+
+- [ ] **Step 3 : Non-régression `Date` et `DateRange`**
+
+Run: `npx vitest run app/components/malio/date/Date.test.ts app/components/malio/date/DateRange.test.ts`
+Expected: PASS (21 + 17). La cellule n° reste un `<div>` non interactif quand `interactiveWeekNumber` est `false`.
+
+- [ ] **Step 4 : Lint** — `npx eslint app/components/malio/date/internal/MonthGrid.vue` → 0 erreur
+
+- [ ] **Step 5 : Commit**
+
+```bash

+**Couverture spec :** `dateWeek.ts` (mondayOf/sundayOf/toIsoWeek/isoWeekToMonday/isValidIsoWeek/formatWeekDisplay) ✓ T1 ; `MonthGrid` `interactiveWeekNumber`+`markedWeekStart`+`data-week-start`/`data-marked`+weekSelectable ✓ T2 ; `DateWeek` API + un clic + hover semaine + repère + clear + min/max overlap + invalide→null ✓ T3 ; affichage `"Semaine 21 (...)"` ✓ T1/T3 ; story+playground ✓ T4. modelValue `YYYY-Www` ✓.
+
+**Placeholders :** aucun ; code complet.
+
+**Cohérence des types :** `toIsoWeek(iso)→string`, `isoWeekToMonday(week)→string|null`, `mondayOf`/`sundayOf(iso)→string`, `formatWeekDisplay(week)→string` définis T1, consommés T3. `MonthGrid` props `interactiveWeekNumber`/`markedWeekStart` T2 → passées par `DateWeek` T3. Events `select`/`hover` (iso jour) réutilisés ; `DateWeek.onSelect` mappe via `toIsoWeek`, `onHover` via `mondayOf`. `WeekRow` importé de `useMonthMatrix` (déjà exporté). Le rendu pilule s'appuie sur `rangeStart`/`rangeEnd` (inchangés) → `Date`/`DateRange` non impactés.
+
+**Écart assumé :** `MonthGrid` gagne `data-week-start`/`data-marked` (testabilité), conforme à la spec.

+# MalioDateTime Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ajouter un composant `MalioDateTime` (date + heure dans un seul champ) à la famille temporelle de `@malio/layer-ui`, en version intérimaire avec `<input type="time">` natif.
+
+**Architecture:** Fine enveloppe autour du shell `internal/CalendarField.vue` (comme `MalioDate`). Le slot popover contient `MonthGrid` (jour) + un `<input type="time">` (heure) sous la grille. La valeur émise est l'ISO naïf `"YYYY-MM-DDTHH:MM:00"`. Logique de découpe/recomposition dans un nouveau composable `datetimeFormat.ts`.
+
+**Tech Stack:** Vue 3 `<script setup lang="ts">`, TypeScript strict, Tailwind (`m-*`), `tailwind-merge`, Vitest + @vue/test-utils (jsdom).
+
+**Conventions (rappel) :** Conventional Commits **avec espace avant `:`**, type minuscule, suffixe ticket `(#MUI-33)`, pas de préfixe `[#...]`. Terminer par `Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>`. Le hook pre-commit est flaky (timeouts WSL2) → après vérification ciblée `npx vitest run <chemin>`, committer avec `--no-verify`.

+
+Ouvrir `COMPONENTS.md`, repérer la section `MalioDate` (ou la famille date) et ajouter une section `MalioDateTime` calquée dessus, documentant :

+- `modelValue` : `string | null`, format `"YYYY-MM-DDTHH:MM:00"` (ISO naïf sans fuseau ; Symfony applique son fuseau).
+- Table des props identique à `MalioDate` (ajouter la note sur `min`/`max` bornant la date).
+- Émission `update:modelValue`.
+- Exemple d'usage :
+
+```vue
+<MalioDateTime v-model="rdv" label="Date et heure du rendez-vous" />
+<!-- rdv === "2026-05-20T14:30:00" -->

+- Note : le sélecteur d'heure est intérimaire et sera remplacé par un composant dédié (maquette à venir).
+
+Respecter le style et la structure exacts des sections existantes (titres, tableaux markdown).
+
+- [ ] **Step 2 : Ajouter l'entrée CHANGELOG.md**

+# MalioModal Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ajouter un composant `MalioModal` (dialogue modal centré) autonome à `@malio/layer-ui`, sans modifier le Drawer existant.
+
+**Architecture:** Composant Vue SFC unique `app/components/malio/modal/Modal.vue`, auto-importé comme `<MalioModal>`. Réimplémente sa propre logique (Teleport, focus-trap, scroll-lock partagé via compteur module-level, pattern contrôlé/non-contrôlé, transition fade+scale) en s'inspirant du Drawer. Structure : header fixe / body scrollable / footer fixe.
+
+**Tech Stack:** Nuxt 4 layer, Vue 3 `<script setup lang="ts">`, Tailwind (tokens `m-*`), `tailwind-merge`, `@iconify/vue`, Vitest + `@vue/test-utils` (jsdom), Histoire.
+
+**Spec:** `docs/superpowers/specs/2026-05-26-modal-design.md`
+
+**Conventions projet à respecter :**
+- Commits Conventional **avec espace avant les `:`** : `feat : … (#MUI-36)`, `docs : …`, `test : …`. Type en minuscules, pas de préfixe `[#…]`. Finir par la ligne `Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>`.
+- Le hook pre-commit lance lint + ~595 tests et **time out de façon flaky** sous WSL2. Pattern : réessayer ; après 2 échecs flaky (échecs différents d'un run à l'autre), vérifier les tests ciblés à la main (`npx vitest run <chemin>`) puis committer avec `--no-verify`.
+- Story : nom de fichier sous un dossier (`story/modal/modal.story.vue`) ; `defineOptions({ name: 'ModalStory' })` pour éviter `vue/multi-word-component-names`.
+
+**File Structure:**
+- Create `app/components/malio/modal/Modal.vue` — le composant (≈ taille du Drawer).
+- Create `app/components/malio/modal/Modal.test.ts` — tests colocalisés.
+- Create `.playground/pages/composant/modal/modal.vue` — page de démo (route `/composant/modal/modal`).
+- Modify `.playground/playground.nav.ts` — ajout de l'entrée nav dans la section `NAVIGATION`.
+- Create `app/story/modal/modal.story.vue` — story Histoire.
+- Modify `COMPONENTS.md` — section `## MalioModal` (insérée après la section `## MalioDrawer`).
+- Modify `CHANGELOG.md` — ligne sous `### Added`.

+# MalioDate — Design Spec
+
+Composant de sélection de date avec champ + popover calendrier. Première brique d'une famille de pickers temporels (futurs `DateRange`, `DateTime`).
+
+**Ticket :** MUI-33
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+
+## Périmètre v1
+
+Sélection d'une date unique via un calendrier. Le champ est **readonly** (clic uniquement, pas de saisie clavier en v1). Locale FR hardcodée, semaine commençant le lundi.
+
+**Inclus en v1 :**
+- Affichage `JJ/MM/AAAA` dans le champ, valeur ISO `YYYY-MM-DD` en `modelValue`
+- Surlignage du jour sélectionné et du jour "aujourd'hui"
+- Jours du mois précédent/suivant affichés grisés mais cliquables (naviguent vers le mois cible)
+- Bornes `min` / `max` (jours hors bornes désactivés)
+- Bouton effacer (croix) si `clearable`
+- Vue mois (grille 4×3) accessible via clic sur `Mois Année ⌄` dans le header
+- Numéros de semaine ISO 8601 dans une colonne à fond `m-primary/10`
+
+**Reporté à plus tard :**
+- Saisie clavier dans le champ (parsing `JJ/MM/AAAA` manuel)
+- Navigation clavier dans la grille (flèches, Enter, Escape)
+- Vue années (sélection rapide d'une année)
+- Prop `disabledDates` (prédicat ou array)
+- i18n (autres langues)
+
+## Architecture
+
+Composant public unique `<MalioDate>` (autoimporté depuis `app/components/malio/date/Date.vue`), composé de sous-composants internes et de modules utilitaires colocalisés.
+
+```
+app/components/malio/date/
+  Date.vue                       # composant public (orchestration)
+  Date.test.ts
+  internal/
+    CalendarHeader.vue           # header mois/année + chevrons + toggle vue
+    MonthGrid.vue                # grille 6×7 jours + colonne semaine
+    MonthPicker.vue              # grille 4×3 mois
+  composables/
+    useMonthMatrix.ts            # calcule la matrice 6×7 + n° semaines ISO
+    dateFormat.ts                # fonctions pures de format/parsing/validation
+    useCalendarPopover.ts        # état ouvert/fermé + click outside
+```
+
+Les sous-composants `internal/` ne sont pas destinés à être consommés directement. Ils seront réutilisés par `DateRange` et `DateTime` à venir.
+
+## Type `modelValue`
+
+`string | null`, au format ISO `YYYY-MM-DD`. Le composant interne convertit en affichage `JJ/MM/AAAA` via `dateFormat.formatIsoToDisplay()`. Cette représentation a été retenue pour :
+- Cohérence avec `<MalioTime>` qui émet déjà une string (`"HH:MM"`)
+- Sérialisation directe vers une API REST/JSON sans conversion
+- Pas de piège de fuseau horaire (un objet `Date` JS porte une heure + un fuseau)
+- Comparaison lexicographique = comparaison chronologique (utile pour `min`/`max`)
+
+## Props
+
+| Prop | Type | Défaut | Description |
+|------|------|--------|-------------|
+| `id` | `string` | auto-généré | Identifiant HTML du champ |
+| `name` | `string` | `''` | Attribut `name` pour les `<form>` |
+| `label` | `string` | `''` | Label flottant |
+| `modelValue` | `string \| null` | `undefined` | Date ISO `YYYY-MM-DD` (v-model) |
+| `placeholder` | `string` | `'JJ/MM/AAAA'` | Placeholder du champ |
+| `required` | `boolean` | `false` | Attribut required |
+| `disabled` | `boolean` | `false` | Verrouille champ et calendrier |
+| `readonly` | `boolean` | `false` | Affiche la valeur mais bloque l'ouverture |
+| `hint` | `string` | `''` | Texte d'aide sous le champ |
+| `error` | `string` | `''` | Message d'erreur (bordure et texte rouges) |
+| `success` | `string` | `''` | Message succès (bordure et texte verts) |
+| `min` | `string` | `undefined` | Borne inférieure incluse, format ISO |
+| `max` | `string` | `undefined` | Borne supérieure incluse, format ISO |
+| `clearable` | `boolean` | `true` | Affiche une croix pour effacer la valeur |
+| `inputClass` | `string` | `''` | Override classes input (twMerge) |
+| `labelClass` | `string` | `''` | Override classes label (twMerge) |
+| `groupClass` | `string` | `''` | Override classes wrapper (twMerge) |
+
+Si `min`/`max` sont invalides (format incorrect ou `min > max`), ils sont ignorés silencieusement avec un warning console en dev.
+
+## Events
+
+| Event | Payload | Description |
+|-------|---------|-------------|
+| `update:modelValue` | `string \| null` | Date ISO sélectionnée, ou `null` si effacée |
+
+## Slots
+
+Aucun slot en v1. L'icône calendrier est fixée (`mdi:calendar-outline`).
+
+## Sous-composants internes
+
+### `CalendarHeader.vue`
+
+Affiche la barre du haut du popover : `[‹] Mois Année [⌄] [›]`.
+
+**Props :**
+- `viewMode: 'days' | 'months'`
+- `currentMonth: number` (0-11)
+- `currentYear: number`
+
+**Events :**
+- `prev` — chevron gauche (interprété par le parent : mois précédent en vue jours, année précédente en vue mois)
+- `next` — chevron droit (idem)
+- `toggle-view` — clic sur le bouton central
+
+### `MonthGrid.vue`
+
+Rend la grille 6 lignes × 8 colonnes (semaine + 7 jours).
+
+**Props :**
+- `month: number` (0-11)
+- `year: number`
+- `selectedDate?: string | null` (ISO)
+- `min?: string` (ISO)
+- `max?: string` (ISO)
+
+**Events :**
+- `select` payload `string` — date ISO `YYYY-MM-DD` du jour cliqué
+
+Utilise `useMonthMatrix(month, year)` pour générer les 6 lignes. La grille fait toujours 6 lignes (forcé) pour stabiliser la hauteur du popover entre les mois.
+
+### `MonthPicker.vue`
+
+Rend la grille 4×3 des mois.
+
+**Props :**
+- `selectedMonth?: number` (0-11, mois courant à surligner)
+
+**Events :**
+- `select` payload `number` (0-11)
+
+Pas de gestion `min`/`max` au niveau mois en v1 — `MonthGrid` filtrera les jours hors bornes au retour vue jours.
+
+## Composables
+
+### `useMonthMatrix.ts`
+
+```ts
+type DayCell = {
+  isoDate: string        // "YYYY-MM-DD"
+  day: number            // 1-31
+  isCurrentMonth: boolean
+  isToday: boolean
+}
+
+type WeekRow = {
+  weekNumber: number     // ISO 8601, 1-53
+  days: DayCell[]        // toujours 7, Lun → Dim
+}
+
+function useMonthMatrix(
+  month: Ref<number>,
+  year: Ref<number>
+): { weeks: ComputedRef<WeekRow[]> }
+```
+
+Le premier jour de la grille est le lundi de la semaine contenant le 1er du mois affiché. La grille fait **toujours** 6 lignes (`WeekRow[]` de longueur 6), au besoin en débordant sur le mois suivant.
+
+Les numéros de semaine suivent **ISO 8601** : la semaine 1 contient le premier jeudi de l'année.
+
+### `dateFormat.ts`
+
+Module de fonctions pures, **pas un composable réactif**. Le nommage sans préfixe `use` reflète sa nature.
+
+```ts
+function formatIsoToDisplay(iso: string | null): string
+// "2026-05-19" → "19/05/2026", null/invalide → ""
+
+function parseDisplayToIso(display: string): string | null
+// "19/05/2026" → "2026-05-19", invalide → null
+
+function isValidIso(iso: string): boolean
+// "2026-05-19" → true, "2026-13-45" → false
+
+function isDateInRange(iso: string, min?: string, max?: string): boolean
+// Comparaison lexicographique (= chronologique pour ISO)
+```
+
+`parseDisplayToIso` est écrit dès la v1 même si non utilisé (le champ est readonly) — il sera réutilisé en v2 quand on rendra le champ éditable.
+
+### `useCalendarPopover.ts`
+
+```ts
+function useCalendarPopover(rootRef: Ref<HTMLElement | null>): {
+  isOpen: Ref<boolean>
+  viewMode: Ref<'days' | 'months'>
+  open: () => void
+  close: () => void
+  toggleView: () => void
+}
+```
+
+- `isOpen` et `viewMode` reset à `false` / `'days'` à la fermeture
+- Listener `mousedown` global attaché à `onMounted`, retiré à `onBeforeUnmount`
+- Fermeture si le clic est hors de `rootRef`
+- Pas de gestion clavier en v1
+
+## Comportements détaillés
+
+### Ouverture du popover
+
+Clic sur le champ ou l'icône calendrier (sauf si `disabled` ou `readonly`) → `open()`. Vue initiale :
+- Si `modelValue` valide → grille du mois de cette date
+- Sinon → grille du mois courant (`new Date()`)
+
+Le champ passe en mode "popover ouvert" : bordure du bas retirée, `rounded-b-none`, bordure latérale colorée (`m-primary` ou `m-danger`/`m-success` selon état).
+
+### Sélection d'un jour (vue jours)
+
+Clic sur une cellule jour cliquable :
+1. Émission `update:modelValue` avec la date ISO
+2. Fermeture du popover
+3. Réaffichage du champ avec la valeur formatée `JJ/MM/AAAA`
+
+Cas spéciaux :
+- Jour hors mois courant : sélection normale, le popover se ferme (peu importe que la vue interne saute au mois cible, elle n'est plus visible)
+- Jour hors `min`/`max` : non cliquable, `cursor-not-allowed`, pas d'émission
+- Re-clic sur la date déjà sélectionnée : ré-émission de la même valeur, popover ferme
+
+### Navigation chevrons (vue jours)
+
+- Chevron gauche : `currentMonth -= 1` (décembre + `year -= 1` si on était en janvier)
+- Chevron droit : symétrique
+- Pas de bornage de navigation par `min`/`max` — on peut naviguer où on veut, seuls les jours sont désactivés
+
+### Bascule vers la vue mois
+
+Clic sur `Mois Année ⌄` → `toggleView()` → `viewMode = 'months'`.
+
+En vue mois :
+- Header inchangé visuellement, mais les chevrons naviguent désormais l'**année** (`year ± 1`)
+- Le bouton central reste cliquable : un nouveau clic ramène à `viewMode = 'days'` (toggle binaire, validé Q4b)
+- Clic sur un mois dans la grille 4×3 → `currentMonth = mois cliqué`, retour `viewMode = 'days'` sans sélection de date
+
+### Fermeture sans sélection
+
+Clic en dehors du champ ET du popover → `close()`. `modelValue` inchangé. L'état interne (`currentMonth`, `currentYear`, `viewMode`) est **reset à la prochaine ouverture** selon la règle "Ouverture du popover" (pas de mémorisation).
+
+### Bouton effacer
+
+Si `modelValue !== null && clearable && !disabled && !readonly` :
+- Une croix `mdi:close` apparaît à gauche de l'icône calendrier
+- Clic émet `null` et `stopPropagation` pour ne pas ouvrir le popover
+
+### États
+
+- `disabled` : opacity réduite, curseur not-allowed, clic sans effet, croix masquée
+- `readonly` : affichage normal, clic sans effet sur l'ouverture, croix masquée
+
+### Synchronisation `modelValue` externe
+
+Si le parent change `modelValue` programmatiquement :
+- Le champ se met à jour (re-format)
+- Si le popover est ouvert, la vue saute au mois de la nouvelle valeur
+- Si la nouvelle valeur a un format invalide, le composant traite comme `null` et log un warning console en dev
+
+## Style / CSS
+
+### Popover
+
+- `min-w-[320px]`, hauteur fixe ~`360px` (6 semaines × ~38px + header)
+- Position : `absolute top-[calc(100%-4px)] left-0 z-20`
+- `bg-white border border-t-0` (couleur selon état : `m-primary` / `m-danger` / `m-success`)
+- `rounded-b-md`
+- Transition : `opacity` 150ms à l'apparition, respect `prefers-reduced-motion`
+
+### Header
+
+- Hauteur `h-12`, `border-b border-m-primary/20`
+- Chevrons (`mdi:chevron-left` / `mdi:chevron-right`) : 20px, padding cliquable 8px, `hover:bg-m-primary/10 rounded`
+- Texte central : `text-base font-medium`, cliquable, `mdi:chevron-down` 16px à côté
+
+### Grille jours
+
+- En-tête `Sem | Lun | Mar | Mer | Jeu | Ven | Sam | Dim` : `text-xs uppercase text-m-muted font-medium`, 32px de hauteur
+- Cellule : `w-10 h-10 text-sm`, centrée
+- Colonne semaine : `bg-m-primary/10`, `text-m-primary/70`, non cliquable
+- Jour du mois courant : `text-black`
+- Jour hors mois : `text-m-muted/50`
+- Jour "aujourd'hui" : `border border-m-primary`, `text-m-primary font-semibold`
+- Jour sélectionné : `bg-m-primary text-white font-medium rounded-full` (prime sur "aujourd'hui")
+- Jour hors `min`/`max` : `text-m-muted/30 cursor-not-allowed`, non cliquable
+- Hover : `hover:bg-m-primary/10 rounded-full`
+
+### Grille mois (MonthPicker)
+
+- `grid grid-cols-4 gap-2 p-3`
+- Cellule : `py-3 text-sm rounded`
+- Libellés : `Janv | Févr | Mars | Avr | Mai | Juin | Juil | Août | Sept | Oct | Nov | Déc`
+- Mois sélectionné : `bg-m-primary text-white`
+- Hover : `hover:bg-m-primary/10`

+Reprend le pattern de `<MalioInputAutocomplete>` : label flottant, bordure `m-muted` au repos, `m-primary` au focus/open, `m-danger`/`m-success` selon état.
+
+- Icône calendrier `mdi:calendar-outline` 20px, à droite, couleur dynamique selon état
+- Croix d'effacement `mdi:close` 16px, à gauche de l'icône, `text-m-muted hover:text-black`
+
+## Accessibilité
+
+- `aria-invalid` synchronisé sur `error`
+- `aria-describedby` lié au texte de `hint`/`error`/`success`
+- `aria-expanded` sur le champ pour signaler l'état du popover
+- `aria-haspopup="dialog"` sur le champ
+- Label `<label for>` lié au champ
+- Cellules jour : `role="button"`, `aria-label="19 mai 2026"` (jour en toutes lettres pour les lecteurs d'écran)
+- Cellules désactivées : `aria-disabled="true"`
+- Navigation clavier dans la grille : **reportée v2** (Escape, flèches, Enter)
+
+## Tests
+
+### `Date.test.ts` (~30 cas)
+
+Tests groupés par `describe` :
+- **Rendu** : label, placeholder, icône calendrier, affichage de la valeur formatée
+- **Popover** : ouverture au clic, fermeture au click outside, vue initiale selon `modelValue`
+- **Navigation** : chevrons en vue jours, passage décembre↔janvier avec changement d'année
+- **Sélection** : émission ISO correcte, fermeture après sélection, sélection d'un jour hors mois
+- **Bornes** : jours hors `min`/`max` non cliquables, comparaison ISO
+- **Vue mois** : bascule, chevrons en vue mois naviguent l'année, clic mois retourne en vue jours
+- **Clearable** : présence/absence de la croix, émission `null`, pas d'ouverture
+- **États** : `disabled` et `readonly` bloquent l'ouverture
+- **A11y** : `aria-invalid`, `aria-describedby`
+- **Synchro externe** : changement de `modelValue` programmatique
+
+### `useMonthMatrix.test.ts` (~10 cas)
+
+- Mois standard (mai 2026) produit 6×7 cellules
+- Mois commençant un lundi (toutes les cases du premier lundi sont du mois courant)
+- Mois finissant un dimanche
+- Année bissextile (février 2024 : 29 jours)
+- Numéro de semaine ISO en début d'année (janvier 2026 commence en semaine 1 ou 52/53 de 2025 ?)
+- Numéro de semaine ISO en fin d'année
+
+### `dateFormat.test.ts` (~10 cas)
+
+- `formatIsoToDisplay` : nominal, null, format invalide
+- `parseDisplayToIso` : nominal, format invalide, jour ou mois hors borne
+- `isValidIso` : nominal, faux positifs (32 jours, mois 13)
+- `isDateInRange` : sans bornes, avec min seul, avec max seul, avec les deux
+
+Helper `mountComponent(props)` reprend le pattern existant des autres tests Malio. Environnement Vitest + jsdom (déjà configurés).
+
+## Story Histoire `Date.story.vue`
+
+Dans `app/story/date/Date.story.vue`. Variants :
+1. **Default** — vierge, label "Date de naissance"
+2. **Avec valeur initiale** — `modelValue="2026-05-19"`
+3. **Avec min/max** — borné aujourd'hui → +30 jours, label "Date du rendez-vous"
+4. **États** — disabled, readonly, error, success, hint
+5. **Non-clearable** — `clearable=false`
+6. **Required** — avec error si vide
+7. **Override de classes** — `inputClass`, `groupClass` custom
+
+## Playground `.playground/pages/composant/date.vue`
+
+Page de test dev :
+- Un `<MalioDate>` standalone
+- Affichage de la valeur courante en dessous
+- Boutons pour reset (`value = null`) et forcer une date (`value = '2026-12-25'`)
+- Un cas avec `min`/`max`
+
+Lien ajouté dans `.playground/pages/index.vue`.
+
+## Découpage de l'implémentation
+
+Le plan d'implémentation (généré ensuite via `writing-plans`) découpera en étapes ordonnées :
+1. Composables purs (`dateFormat`, `useMonthMatrix`, `useCalendarPopover`) + leurs tests
+2. Sous-composants internes (`CalendarHeader`, `MonthGrid`, `MonthPicker`)
+3. Composant public `Date.vue`
+4. Tests d'intégration `Date.test.ts`
+5. Story Histoire + page playground

+# MalioDateRange — Design Spec
+
+Composant de sélection d'une **période** (date début / date fin) via un champ + popover calendrier. Deuxième brique de la famille temporelle, construite sur un shell partagé extrait de `MalioDate`.
+
+**Ticket :** MUI-33 (suite)
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+**Spec liée :** `docs/superpowers/specs/2026-05-19-datepicker-design.md`
+
+## Contexte & roadmap
+
+`MalioDate` (sélection simple) est déjà livré. Suivront `DateWeek` et `DateTime`. Les 4 composants partagent le **même champ + popover + header + vue mois** ; seule la sélection diffère. On extrait donc un shell réutilisable `CalendarField` (Approche 3 retenue parce que la famille comptera 4 variantes — la duplication de coquille ×4 et la maintenance front en parallèle sont le vrai risque).
+
+## Périmètre
+
+Sélection d'une période sur **un seul mois** affiché (popover = largeur du champ, comme `Date`). Visuellement identique à `Date`, sauf :
+- on sélectionne **deux dates** (début/fin)
+- les jours **entre** les bornes ont un fond `bg-m-primary-light` (bleu clair)
+- les bornes (start/end) gardent le cercle plein `bg-m-primary`
+- **aperçu au survol** (hover preview) de la plage pendant la sélection
+
+**Inclus :** sélection 2 clics, auto-inversion, hover preview, surlignage de plage (demi-barre aux bornes), bornes `min`/`max`, effacement, vue mois conservée.
+
+**Reporté :** deux mois côte à côte, ajustement de la borne la plus proche au 3e clic (on garde le reset standard), saisie clavier, navigation clavier.
+
+## Architecture (Approche 3 — shell partagé)

+Flux :
+
+```
+DateRange.vue (enveloppe)
+ ├─ état de sélection range ({start,end} + pendingStart + hoverDate)
+ ├─ displayValue ("19/05/2026 - 25/05/2026")
+ └─ <CalendarField :display-value :sync-to=start ... @clear @close>
+        ├─ champ + popover (useCalendarPopover) + navigation (useCalendarView)
+        ├─ header + MonthPicker (viewMode='months')
+        └─ <slot :current-month :current-year :close>   ← viewMode='days'
+               └─ <MonthGrid> mode range (rangeStart/rangeEnd/previewDate, @select, @hover)
+```
+
+`CalendarField` ne connaît **rien** de la sélection : il gère champ, ouverture, navigation, et expose `{ currentMonth, currentYear, close }` au slot. Chaque enveloppe branche son `MonthGrid` et décide quand appeler `close()`.
+
+## `useCalendarView.ts`
+
+```ts
+function useCalendarView(viewMode: Ref<'days' | 'months'>): {
+  currentMonth: Ref<number>          // 0-11
+  currentYear: Ref<number>
+  goToPrev: () => void               // viewMode==='months' ? année-1 : mois-1 (roulement déc↔jan)
+  goToNext: () => void               // idem +1
+  selectMonth: (m: number) => void   // currentMonth = m
+  syncToIso: (iso: string | null) => void  // mois/année depuis un ISO valide, sinon mois courant
+}
+```
+
+Reprend la logique `onPrev`/`onNext`/`syncViewToValue` actuelle de `Date.vue`. Pur, testable seul.
+
+## `CalendarField.vue` (shell)
+
+**Props :**
+
+| Prop | Type | Défaut | Description |
+|------|------|--------|-------------|
+| `displayValue` | `string` | **requis** | Texte affiché dans le champ (`''` si rien/incomplet) |
+| `syncTo` | `string \| null` | **requis** | ISO servant à caler le mois à l'ouverture |
+| `id`,`name`,`label`,`placeholder` | `string` | `''` / `'JJ/MM/AAAA'` | Champ |
+| `required`,`disabled`,`readonly` | `boolean` | `false` | États |
+| `hint`,`error`,`success` | `string` | `''` | Messages |
+| `clearable` | `boolean` | `true` | Croix d'effacement |
+| `inputClass`,`labelClass`,`groupClass` | `string` | `''` | Overrides twMerge |
+
+**Events :**
+
+| Event | Payload | Description |
+|-------|---------|-------------|
+| `clear` | — | Croix cliquée → l'enveloppe met son `modelValue` à `null` |
+| `close` | — | Popover fermé (clic dehors ou programmatique) → l'enveloppe annule sa sélection en cours |
+
+**Slot par défaut** (scoped, rendu quand `viewMode==='days'`) : `{ currentMonth: number, currentYear: number, close: () => void }`.
+
+**Comportement** (repris à l'identique de l'actuel `Date.vue`) : input readonly, label flottant (bleu à l'ouverture), icône calendrier, croix (si `clearable && displayValue && !disabled && !readonly`), grossissement calibré 48px, bordures/états, popover ombré largeur champ collé sous le champ, header (`prev`/`next`→`useCalendarView`, `toggle`→`useCalendarPopover.toggleView`), `MonthPicker` en vue mois (clic mois → `selectMonth` + retour vue jours), `syncToIso(syncTo)` à l'ouverture + watch resync. `isFilled` dérivé de `displayValue.length > 0`.
+
+## `dateRange.ts` (helpers purs)
+
+```ts
+type DateRangeValue = { start: string; end: string }
+
+function normalizeRange(a: string, b: string): DateRangeValue
+// réordonne pour garantir start ≤ end
+
+function resolveRangeBounds(
+  start: string | null, end: string | null, preview: string | null,
+): { lo: string; hi: string } | null
+// pas de start → null ; end committé prioritaire, sinon preview, sinon {lo:start,hi:start}
+
+type DayRangeRole = 'none' | 'single' | 'start' | 'end' | 'in-range'
+function dayRangeRole(iso: string, bounds: { lo: string; hi: string } | null): DayRangeRole
+```
+
+## `MonthGrid.vue` — extension
+
+**Nouvelles props (optionnelles) :** `rangeStart?`, `rangeEnd?`, `previewDate?` (ISO ou null). Mode plage actif dès que `rangeStart` est passé ; sinon mode simple (`selectedDate`, comportement actuel inchangé).
+
+**Nouvel event :** `hover` payload `string | null` — `mouseenter` d'un jour → ISO, `mouseleave` de la grille → `null`.
+
+**Attribut testabilité :** chaque bouton jour porte `:data-range-role="role"` (`none`/`single`/`start`/`end`/`in-range`).
+
+**Rendu d'un jour en mode plage** — bouton `relative` superposant 2 couches :
+1. Barre de fond absolue `bg-m-primary-light` : `in-range` → pleine largeur (`inset-0`) ; `start` → moitié droite (`left-1/2 right-0`) ; `end` → moitié gauche (`left-0 right-1/2`) ; `single`/`none` → aucune.
+2. Cercle (span `h-10 w-10`) au-dessus : `start`/`end`/`single` → `bg-m-primary` blanc ; `in-range` → transparent, texte noir ; `none` → rendu simple actuel (aujourd'hui, hors-mois…).
+
+La barre passe sous les cercles, colonnes jointives → plage continue démarrant/finissant au centre des cercles.
+
+## `DateRange.vue` (enveloppe)
+
+**Props :** identiques à `Date` sauf `modelValue?: { start: string; end: string } | null`. (`id`,`name`,`label`,`placeholder`,`required`,`disabled`,`readonly`,`hint`,`error`,`success`,`min`,`max`,`clearable`,`inputClass`,`labelClass`,`groupClass`.)
+
+**Emit :** `update:modelValue` → `{ start: string; end: string } | null`.
+
+**État interne :**
+```ts
+pendingStart = ref<string | null>(null)   // 1er clic en attente du 2e
+hoverDate    = ref<string | null>(null)   // survol pour le preview
+const isSelecting = computed(() => pendingStart.value !== null)
+```
+
+**Passé au `<MonthGrid>` :**
+```ts
+rangeStart  = isSelecting ? pendingStart : (modelValue?.start ?? null)
+rangeEnd    = isSelecting ? null         : (modelValue?.end ?? null)
+previewDate = isSelecting ? hoverDate    : null
+// + :min :max :month :year (slot)
+```
+
+**`displayValue` :** `''` pendant la sélection (1 seul jour choisi) ; `"JJ/MM/AAAA - JJ/MM/AAAA"` si plage complète ; `''` sinon. **`syncTo`** = `modelValue?.start ?? null`.
+
+**Machine à états :**
+```
+onSelectDay(iso):
+  si pendingStart === null:                 # 1er clic (ou reset après plage complète)
+      pendingStart = iso ; hoverDate = null
+  sinon:                                     # 2e clic → complète
+      { start, end } = normalizeRange(pendingStart, iso)   # auto-inversion
+      emit('update:modelValue', { start, end })
+      pendingStart = null ; hoverDate = null
+      close()                                # ferme le popover (slot)
+
+onHover(iso):                                # émis par MonthGrid
+  si isSelecting: hoverDate = iso            # preview seulement pendant la sélection
+
+onClose():                                   # CalendarField émet 'close'
+  pendingStart = null ; hoverDate = null     # annule la sélection en cours, modelValue inchangé
+
+onClear():                                   # CalendarField émet 'clear'
+  emit('update:modelValue', null)
+  pendingStart = null ; hoverDate = null
+```
+
+- **3e clic** (plage complète) : `pendingStart===null` → nouveau `start`, ancienne plage masquée pendant la sélection (`rangeEnd=null`), remplacée à la complétion.
+- **min/max** : `MonthGrid` désactive les jours hors bornes → les 2 clics sont contraints.
+- **modelValue invalide** (start/end mal formés) : traité comme `null` + warning dev.
+
+## Refacto `Date.vue`
+
+API publique **inchangée**. Devient une enveloppe (~80 lignes) :
+```vue
+<CalendarField :display-value="displayValue" :sync-to="modelValue ?? null" ...props
+  @clear="emit('update:modelValue', null)">
+  <template #default="{ currentMonth, currentYear, close }">
+    <MonthGrid :month="currentMonth" :year="currentYear"
+      :selected-date="modelValue ?? null" :min="min" :max="max"
+      @select="(iso) => { emit('update:modelValue', iso); close() }" />
+  </template>
+</CalendarField>
+```
+`displayValue = formatIsoToDisplay(modelValue)`. Watch modelValue invalide → warning dev (conservé). Mode simple : pas de `@close` (rien à annuler), pas de `@hover`.
+
+**Les 21 tests de `Date.test.ts` doivent passer sans modification** : tous les `data-test` sont rendus par `CalendarField`/`MonthGrid`, donc présents dans le DOM monté de `Date`. C'est le filet de sécurité du refacto.
+
+## Tests
+
+### `dateRange.test.ts` (~12)
+- `normalizeRange` : ordonné, inversé, égal
+- `resolveRangeBounds` : pas de start → null ; start seul → `{lo,hi}=start` ; start+end ordonné ; start+preview ; preview avant start (inversion) ; end prioritaire sur preview
+- `dayRangeRole` : none (pas de bornes / hors plage), single (lo===hi), start, end, in-range
+
+### `useCalendarView.test.ts` (~8, fake timers)
+- mois/année initiaux = aujourd'hui ; `goToNext`/`goToPrev` vue jours (+ roulement déc↔jan avec année) ; `goToNext`/`goToPrev` vue mois (année ±1) ; `selectMonth` ; `syncToIso` valide / null
+
+### `Date.test.ts`
+Inchangé — doit rester vert (filet du refacto).
+
+### `DateRange.test.ts` (~18)
+- Rendu : label, icône, `"19/05/2026 - 25/05/2026"` si modelValue, champ vide sinon
+- Ouverture popover, vue sur le mois du `start`
+- 1er clic → pas d'émission ; 2e clic → émet `{start,end}` + ferme
+- 2e clic avant le 1er → auto-inversion (start ≤ end)
+- Même jour ×2 → `{start:x, end:x}`
+- 3e clic → repart sur un nouveau start (pas d'émission avant le 2e)
+- Hover pendant sélection → `data-range-role="in-range"` sur jours intermédiaires ; pas de preview hors sélection
+- Rôles : `start`/`end`/`in-range` corrects via `data-range-role`
+- Clic dehors pendant sélection → annulation, `modelValue` inchangé
+- `clear` → émet `null`
+- min/max → jours hors bornes non cliquables
+- a11y : `aria-invalid` sur error
+
+### Story `dateRange.story.vue`

+# MalioDateWeek — Design Spec
+
+Composant de sélection d'une **semaine ISO complète** (lundi→dimanche) via le shell calendrier partagé. Troisième brique de la famille temporelle.
+
+**Ticket :** MUI-33 (suite)
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+**Specs liées :** `2026-05-19-datepicker-design.md`, `2026-05-20-daterange-design.md`
+
+## Périmètre
+
+Sélection d'une semaine entière en **un clic** (sur n'importe quel jour OU le numéro de semaine). Visuellement : la ligne de la semaine se surligne en pilule `bg-m-primary-light` (lundi arrondi gauche, dimanche arrondi droit), exactement comme une plage `DateRange` figée lun→dim. Survol = aperçu de la semaine. La cellule n° de la semaine sélectionnée passe en `bg-m-primary` (repère).
+
+**Inclus :** clic jour/n° → semaine, hover de semaine, surlignage pilule, repère n° semaine, bornes `min`/`max` (semaine sélectionnable si elle chevauche), effacement, vue mois conservée.
+
+**Reporté :** deux mois, saisie/navigation clavier.
+
+## Donnée retournée
+
+`modelValue: string | null` au format **ISO 8601 semaine `YYYY-Www`** (ex. `"2026-W21"`), comme l'`<input type="week">` natif. L'année est l'**année ISO de numérotation** (peut différer de l'année calendaire aux bords d'année). Affichage humain dans le champ : `"Semaine 21 (18/05 → 24/05/2026)"` (le `modelValue` reste `2026-W21`).
+
+## Architecture (Approche 1 — réutilisation du rendu plage)
+
+Une semaine sélectionnée **est** une plage lundi→dimanche : on réutilise le rendu pilule de `MonthGrid` (mode plage) en passant les bornes de la semaine active. Les events `select`/`hover` (jour) sont réutilisés ; l'enveloppe `DateWeek` mappe jour → semaine.

+- Algo ISO 8601 : jeudi de la semaine pour l'année de numérotation ; lundi de la semaine contenant le 4 janvier = semaine 1.

+

+Nouvelles props optionnelles (n'altèrent pas les modes simple/plage) :
+```ts
+interactiveWeekNumber?: boolean   // défaut false
+markedWeekStart?: string | null   // défaut null — lundi de la semaine repère
+```
+
+Quand `interactiveWeekNumber === true` :
+- La cellule n° de semaine devient un `<button>` : `@click` émet `select(week.days[0].isoDate)`, `@mouseenter` émet `hover(week.days[0].isoDate)`. `:disabled` si `!weekSelectable`, où `weekSelectable = week.days.some(d => inRange(d.isoDate))`. `cursor-pointer` si sélectionnable.
+- Repère : si `week.days[0].isoDate === markedWeekStart`, la cellule n° passe en `bg-m-primary text-white` (au lieu de `bg-m-primary-light`).
+
+Toujours (inoffensif hors mode semaine) : la cellule n° porte `:data-week-start="week.days[0].isoDate"` et `:data-marked="week.days[0].isoDate === markedWeekStart"`.
+
+Inchangé : rendu pilule des jours piloté par `rangeStart`/`rangeEnd` ; events `select`/`hover` jour ; quand `interactiveWeekNumber` est `false`, la cellule n° reste un `<div>` non cliquable (aucune régression `Date`/`DateRange`).
+
+## `DateWeek.vue` (enveloppe)
+
+**Props :** identiques à `Date` sauf `modelValue?: string | null` (`YYYY-Www`).
+**Emit :** `update:modelValue` → `string | null`.
+
+**État :**
+```ts
+hoverWeekStart = ref<string | null>(null)
+const validWeek = computed(() =>
+  (props.modelValue && isValidIsoWeek(props.modelValue))
+    ? {monday: isoWeekToMonday(props.modelValue) as string}
+    : null)
+const activeMonday = computed(() => hoverWeekStart.value ?? validWeek.value?.monday ?? null)
+const activeSunday = computed(() => activeMonday.value ? sundayOf(activeMonday.value) : null)
+```
+
+**Passé à `MonthGrid` :** `range-start=activeMonday`, `range-end=activeSunday`, `marked-week-start=validWeek?.monday ?? null`, `interactive-week-number`, `min`, `max`, month/year du slot.
+
+**`displayValue`** = `validWeek ? formatWeekDisplay(modelValue) : ''`. **`syncTo`** = `validWeek?.monday ?? null`.
+
+**Comportement (1 clic) :**
+```
+onSelect(iso, close):            # jour OU n° de semaine (= lundi)
+  emit('update:modelValue', toIsoWeek(iso))
+  hoverWeekStart = null
+  close()
+
+onHover(iso):                    # jour/n° survolé ; null au mouseleave
+  hoverWeekStart = iso ? mondayOf(iso) : null
+
+onClose():  hoverWeekStart = null
+onClear():  emit('update:modelValue', null) ; hoverWeekStart = null
+```
+
+- Survol → toute la ligne en pilule via `activeMonday`.
+- Sélection en un clic → `YYYY-Www` + fermeture.
+- Repère de la semaine committée conservé pendant le survol d'une autre.
+- `modelValue` invalide → traité comme `null` + warning dev.

+# MalioDateTime — Design (version intérimaire)
+
+**Date :** 2026-05-22
+**Ticket :** #MUI-33 (famille Datepicker)
+**Statut :** validé, prêt pour le plan d'implémentation
+
+## Objectif
+
+Ajouter un composant `MalioDateTime` à la famille temporelle de `@malio/layer-ui`, permettant de saisir **une date ET une heure** dans un seul champ avec popover.
+
+Cette version est **intérimaire** : le sélecteur d'heure utilise un `<input type="time">` natif, le temps que la maquette du sélecteur d'heure dédié soit fournie. Le bloc heure est volontairement isolé pour pouvoir être remplacé sans toucher au reste.
+
+## Valeur du modèle
+
+`modelValue: string | null` au format **ISO naïf sans fuseau** : `"YYYY-MM-DDTHH:MM:00"` (ex. `"2026-05-20T14:30:00"`).
+
+- Heure murale locale : un picker n'a pas de notion de fuseau.
+- Symfony (`DateTimeNormalizer`, RFC 3339) parse ce format et applique son fuseau configuré → zéro bug TZ/DST côté front.
+- Les secondes sont toujours `00` (le natif `type="time"` par défaut n'expose pas les secondes).
+- Cohérent avec `MalioDate` (`YYYY-MM-DD`) et `MalioTime` (`HH:MM`).
+
+## Architecture
+
+Fine enveloppe autour du shell partagé `internal/CalendarField.vue`, comme `MalioDate` / `MalioDateRange` / `MalioDateWeek`.
+
+```
+MalioDateTime (Date/DateTime.vue)
+  └─ CalendarField (champ + popover + header + navigation mois)
+       slot #default={ currentMonth, currentYear, close }
+         ├─ MonthGrid          (sélection du jour)
+         └─ <input type="time"> (sélection de l'heure, sous la grille)
+```
+
+Le `close` du slot n'est **pas** appelé sur sélection (contrairement à `MalioDate`) : on a besoin de date ET heure, la fermeture se fait au clic extérieur (déjà gérée par `CalendarField` via `useCalendarPopover`).
+
+## Props
+
+Identiques à `MalioDate` :
+
+| Prop | Type | Défaut | Note |
+|---|---|---|---|
+| `id` | `string` | `''` | |
+| `name` | `string` | `''` | |
+| `label` | `string` | `''` | |
+| `modelValue` | `string \| null` | `undefined` | `"YYYY-MM-DDTHH:MM:00"` |
+| `placeholder` | `string` | `'JJ/MM/AAAA HH:MM'` | |
+| `required` | `boolean` | `false` | |
+| `disabled` | `boolean` | `false` | |
+| `readonly` | `boolean` | `false` | |
+| `hint` | `string` | `''` | |
+| `error` | `string` | `''` | |
+| `success` | `string` | `''` | |
+| `min` | `string` | `undefined` | datetime ou date ; on borne la grille avec la partie date |
+| `max` | `string` | `undefined` | idem |
+| `clearable` | `boolean` | `true` | |
+| `inputClass` / `labelClass` / `groupClass` | `string` | `''` | |
+
+**Émissions :** `update:modelValue: string | null`.
+
+## Affichage du champ
+
+`displayValue` = `formatIsoDateTimeToDisplay(modelValue)` → `"JJ/MM/AAAA HH:MM"` (ex. `20/05/2026 14:30`). Chaîne vide si `modelValue` nul ou invalide.
+
+## Flux de sélection
+
+État : `modelValue` est la source de vérité. Une ref locale `pendingTime: string` (`'HH:MM'` ou `''`) sert de pont quand l'heure est réglée avant qu'un jour soit choisi.
+
+- **Partie date courante** = `splitDateTime(modelValue).date` (ou `null`).
+- **Valeur de l'`<input type="time">`** = `splitDateTime(modelValue).time` si présent, sinon `pendingTime`.
+
+Interactions :
+
+1. **Clic sur un jour `iso`** :
+   - `heureEffective` = partie heure de `modelValue`, sinon `pendingTime`, sinon `'00:00'`.
+   - émet `composeDateTime(iso, heureEffective)` → `"iso T heure:00"`.
+   - le popover **reste ouvert**.
+2. **Changement de l'`<input type="time">` (`hhmm`)** :
+   - si une partie date existe → émet `composeDateTime(datePart, hhmm)`.
+   - sinon → stocke `hhmm` dans `pendingTime` (pas d'émission tant qu'aucun jour n'est choisi).
+   - si `hhmm` est vidé (`''`) et qu'une date existe → on garde la date avec `00:00` ? **Non** : on n'émet rien sur vidage, on conserve la dernière valeur émise (le natif renvoie rarement `''` une fois rempli ; cas négligé pour l'intérim).
+3. **Effacer (croix)** : émet `null`, `pendingTime = ''`.
+
+Bornes `min`/`max` : passées à `MonthGrid` après slice de la partie date (`min?.slice(0, 10)`). Pas de borne sur l'heure dans cette version.
+
+## Composable `composables/datetimeFormat.ts`
+
+Réutilise `isValidIso` de `dateFormat.ts` pour valider la partie date.
+
+```ts
+// "YYYY-MM-DDTHH:MM:00" complet et valide ?
+export function isValidIsoDateTime(s: string): boolean
+
+// "YYYY-MM-DDTHH:MM:00" -> "JJ/MM/AAAA HH:MM" (chaîne vide si invalide/nul)
+export function formatIsoDateTimeToDisplay(s: string | null): string
+
+// "YYYY-MM-DDTHH:MM:00" -> { date: "YYYY-MM-DD" | null, time: "HH:MM" | '' }
+export function splitDateTime(s: string | null): { date: string | null; time: string }
+
+// (date "YYYY-MM-DD", time "HH:MM") -> "YYYY-MM-DDTHH:MM:00"
+export function composeDateTime(date: string, time: string): string
+```
+
+Règles :
+- `isValidIsoDateTime` : regex `^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}$`, partie date valide via `isValidIso`, heure `00–23`, minutes `00–59`, secondes `00–59`.
+- `splitDateTime` : si `s` nul ou ne matche pas le motif datetime → `{ date: null, time: '' }`. Sinon découpe sur `T`, renvoie la date et `HH:MM` (5 premiers car. de la partie heure).
+- `composeDateTime(date, time)` : `${date}T${time}:00`. Si `time` vide → `${date}T00:00:00`.
+- `formatIsoDateTimeToDisplay` : si `!isValidIsoDateTime` → `''`. Sinon `${dd}/${mm}/${yyyy} ${hh}:${min}`.
+
+## Tests
+
+Colocalisés, Vitest + @vue/test-utils (jsdom), `vi.setSystemTime(new Date(2026, 4, 19))` pour déterminisme.
+
+**`datetimeFormat.test.ts`** (helpers purs) :
+- `isValidIsoDateTime` : accepte `"2026-05-20T14:30:00"` ; rejette `"2026-05-20"`, `"2026-13-01T00:00:00"`, `"2026-05-20T24:00:00"`, `"2026-05-20T14:60:00"`, `""`, format sans secondes.
+- `formatIsoDateTimeToDisplay` : `"2026-05-20T14:30:00"` → `"20/05/2026 14:30"` ; nul/invalide → `''`.
+- `splitDateTime` : `"2026-05-20T14:30:00"` → `{ date: "2026-05-20", time: "14:30" }` ; `null` → `{ date: null, time: '' }` ; `"2026-05-20"` (date seule, non datetime) → `{ date: null, time: '' }`.
+- `composeDateTime` : `("2026-05-20", "14:30")` → `"2026-05-20T14:30:00"` ; `("2026-05-20", "")` → `"2026-05-20T00:00:00"`.
+
+**`DateTime.test.ts`** (composant) :
+- Rendu : champ présent, placeholder `JJ/MM/AAAA HH:MM`, `displayValue` correct quand `modelValue` fourni.
+- Ouverture popover au clic → `MonthGrid` + `input[type=time]` visibles.
+- Clic sur un jour sans heure → émet `"<iso>T00:00:00"`, popover reste ouvert.
+- Clic sur un jour avec `pendingTime` réglé d'abord → émet `"<iso>T<pendingTime>:00"`.
+- Changement de l'heure avec date déjà choisie → émet `"<date>T<nouvelleHeure>:00"`.
+- Changement de l'heure sans date → **aucune émission**.
+- `clearable` : croix émet `null`.
+- `min`/`max` datetime → jours hors bornes désactivés dans la grille.
+- Accessibilité : label lié, `aria-invalid` sur erreur.

+# Spec — Composant Accordéon `<MalioAccordion>`
+
+**Date :** 2026-05-26
+**Ticket :** MUI-37
+**Statut :** Validé (design), prêt pour planification
+
+## Contexte & objectif
+
+Ajouter un composant accordéon à `@malio/layer-ui`. Cas d'usage principal :
+un **système de filtres dans un drawer** d'ERP, où plusieurs sections de
+critères (prix, catégorie, marque…) doivent pouvoir être dépliées
+simultanément, chaque section ayant un contenu hétérogène (checkboxes,
+slider, recherche…).
+
+## Décision d'API : composants enfants (compositional)
+
+Plutôt que l'API « tableau `items` + slots » de NuxtUI (qui impose un template
+`#content` unique avec un switch central sur l'item courant), on adopte une
+**API compositionnelle** : un parent `<MalioAccordion>` qui enveloppe des
+enfants `<MalioAccordionItem>`. Chaque section déclare son titre **et** son
+contenu au même endroit, sans switch central, et s'ajoute/se retire
+indépendamment.
+
+Rationale : pour des filtres au contenu hétérogène, c'est nettement plus
+lisible et évolutif. On reste **100 % natif** (pas de dépendance Reka UI,
+contrairement à NuxtUI), cohérent avec le `TabList` maison et les conventions
+du layer (`@iconify/vue`, `twMerge`, props `*Class`).
+
+## Architecture
+
+```
+MalioAccordion        (parent : état d'ouverture, mode, coordination)
+└─ MalioAccordionItem  (enfant : en-tête cliquable + panneau animé + slot)
+```
+
+Le parent **fournit** (`provide`) un contexte d'accordéon ; chaque enfant
+**l'injecte** (`inject`) pour connaître son état d'ouverture et déclencher les
+bascules. Communication via une clé `Symbol` (`InjectionKey`).
+
+**Contexte fourni** (forme indicative) :
+
+```ts
+interface AccordionContext {
+  mode: ComputedRef<'single' | 'multiple'>
+  isOpen: (value: string) => boolean
+  toggle: (value: string) => void
+  register: (value: string, defaultOpen: boolean) => void  // enfant → parent au montage
+  unregister: (value: string) => void
+  baseId: string                                           // pour générer les ids ARIA
+  registerHeader / focus nav helpers                       // pour la navigation flèches
+}
+```
+
+**Fichiers :**
+
+```
+app/components/malio/accordion/Accordion.vue
+app/components/malio/accordion/AccordionItem.vue
+app/components/malio/accordion/Accordion.test.ts
+app/components/malio/accordion/AccordionItem.test.ts
+```
+
+(+ page playground et story Histoire, cf. skill `creating-malio-component`.)
+
+## API publique
+
+### `<MalioAccordion>`
+
+`defineOptions({ name: 'MalioAccordion', inheritAttrs: false })`
+
+| Prop | Type | Défaut | Rôle |
+|------|------|--------|------|
+| `mode` | `'single' \| 'multiple'` | `'multiple'` | Un seul ou plusieurs panneaux ouverts |
+| `modelValue` | `string \| string[]` | `undefined` | v-model des clés ouvertes (`string` en `single`, `string[]` en `multiple`) |
+| `id` | `string` | auto (`useId`) | Base d'id pour les attributs ARIA |
+| `groupClass` | `string` | `''` | Classes du conteneur (fusion `twMerge`) |
+
+**Events :** `update:modelValue(value: string | string[])`
+
+**Pattern contrôlé / non-contrôlé** (convention maison) :
+`isControlled = computed(() => props.modelValue !== undefined)`, avec
+`localValue` en fallback. En non-contrôlé, l'état initial est dérivé des
+enfants ayant `defaultOpen`.
+
+### `<MalioAccordionItem>`
+
+`defineOptions({ name: 'MalioAccordionItem', inheritAttrs: false })`
+
+| Prop | Type | Défaut | Rôle |
+|------|------|--------|------|
+| `title` | `string` | — | Texte de l'en-tête |
+| `value` | `string` | auto (`useId`) | Clé unique (recommandée pour piloter le v-model) |
+| `defaultOpen` | `boolean` | `false` | Ouvert au montage (mode non-contrôlé) |
+| `disabled` | `boolean` | `false` | En-tête non cliquable |
+| `headerClass` | `string` | `''` | Override classes de l'en-tête (`twMerge`) |
+| `panelClass` | `string` | `''` | Override classes du panneau (`twMerge`) |
+
+**Slot par défaut** = contenu du panneau.
+
+## Comportement : mode `single` vs `multiple`
+
+- **`multiple`** (défaut) : `modelValue` est un `string[]`. Basculer une
+  section ajoute/retire sa clé du tableau, sans affecter les autres.
+- **`single`** : `modelValue` est un `string` (clé ouverte, ou `''`/`undefined`
+  si tout fermé). Ouvrir une section ferme la précédente.
+
+L'en-tête minimal : **titre + chevron animé** uniquement. Pas de badge, pas
+d'icône leading, pas de slot d'en-tête custom dans cette version (extensible
+plus tard si besoin métier).
+
+## Animation & rendu
+
+- **Ouverture/fermeture** : transition de hauteur via
+  `grid-template-rows: 0fr → 1fr` sur un wrapper en `overflow: hidden`
+  (gère la hauteur dynamique du contenu sans mesure JS).
+- **Chevron** : `mdi:chevron-down` via `@iconify/vue`, rotation 180° en
+  transition synchronisée avec l'ouverture.
+- **Tokens Malio** : séparateurs `border-m-border`, titre `text-m-text`,
+  `rounded-malio` au besoin. Tout surchargeable via `headerClass` / `panelClass`
+  fusionnés avec `twMerge()`.
+
+## Accessibilité (WAI-ARIA Accordion Pattern)
+
+- En-tête = vrai `<button type="button">` → focusable nativement,
+  Entrée/Espace pour basculer.
+- `aria-expanded` sur le bouton, `aria-controls` → id du panneau.
+- Panneau : `role="region"` + `aria-labelledby` → id du bouton.
+- Sections désactivées : `disabled` + `aria-disabled` sur le bouton.
+- **Navigation clavier ↑/↓** entre les en-têtes (déplacement du focus d'un
+  en-tête à l'autre), conformément au pattern WAI-ARIA. `Home`/`End`
+  optionnels (nice-to-have).
+
+## Tests (Vitest + @vue/test-utils, jsdom)
+
+Helper `mountComponent(props)` colocalisé. Couverture cible :
+
+**Accordion.test.ts**
+- Rendu des enfants (slots).
+- Mode `multiple` : plusieurs sections ouvertes simultanément.
+- Mode `single` : ouvrir une section ferme la précédente.
+- v-model contrôlé : `modelValue` pilote l'état ; émission de `update:modelValue`.
+- Non-contrôlé : `defaultOpen` sur enfants → état initial correct.
+
+**AccordionItem.test.ts**
+- Toggle au clic sur l'en-tête.
+- `disabled` : clic sans effet, attributs `disabled` / `aria-disabled`.
+- Attributs ARIA : `aria-expanded`, `aria-controls`, `role="region"`,
+  `aria-labelledby` correctement liés.
+- Navigation clavier ↑/↓ entre en-têtes.
+- Override de classes via `headerClass` / `panelClass`.
+
+## Livrables documentaires (convention maison)
+
+- Mise à jour de `COMPONENTS.md` (tableau de props + exemples).
+- Mise à jour de `CHANGELOG.md`.
+- Page playground (ajout à `playground.nav.ts`).
+- Story Histoire (`app/story/accordion/`).
+
+## Hors périmètre (YAGNI, V1)
+
+- Badge / compteur de filtres actifs dans l'en-tête.
+- Icône leading.
+- Slot d'en-tête personnalisé.
+- Persistance d'état (localStorage, URL).
+
+Ces éléments pourront être ajoutés ultérieurement si un besoin métier concret
+émerge, sans casser l'API.

+# Design — `MalioModal`
+
+Date : 2026-05-26
+Statut : validé
+
+## Objectif
+
+Ajouter un composant `MalioModal` à `@malio/layer-ui` : un dialogue modal centré sur fond
+assombri. Périmètre initial = **shell générique seul** (pas de variante confirmation/alerte).
+Le consommateur place ce qu'il veut dans les slots.
+
+## Décisions clés
+
+- **Composant autonome** : la Modal réimplémente sa propre logique en s'inspirant du Drawer,
+  **sans modifier le Drawer existant** (zéro risque de régression). Un éventuel refactor vers
+  un composable partagé Drawer/Modal pourra se faire plus tard.
+- **Largeur unique + override** : une largeur par défaut (`max-w-md`), ajustable par le
+  consommateur via la prop `modalClass` (pas de prop `size`).
+- **Footer fixe en bas** : header fixe en haut, body scrollable au milieu (`max-h-[85vh]`),
+  footer fixe en bas séparé par une bordure — structure modale classique (≠ Drawer où le footer
+  est dans la zone scrollable).
+- **Front volontairement simple** pour cette première version.
+
+## Emplacement & livrables
+
+- `app/components/malio/modal/Modal.vue`
+- `app/components/malio/modal/Modal.test.ts` (colocalisé, jsdom)
+- Page playground `.playground/pages/composant/modal/modal.vue`
+- Entrée nav : `{label: 'Modal', to: '/composant/modal/modal'}` ajoutée dans la section
+  **NAVIGATION** de `.playground/playground.nav.ts`, juste après le Drawer
+- Story Histoire `app/story/modal.story.vue`
+- Mise à jour `COMPONENTS.md` (API) et `CHANGELOG.md` (`### Added`)
+
+## Structure (template)
+
+```

+    └ div fixed inset-0 z-50 flex items-center justify-center p-4   ← centre la modal
+       ├ div backdrop (bg-black/40, @click → si dismissable)

+Mêmes props que le Drawer, **sans `side`** ; `drawerClass` → `modalClass`.
+
+### Events
+
+- `update:modelValue(value: boolean)` — pour le `v-model`
+- `close()` — émis à chaque fermeture (croix, backdrop, Échap, fermeture programmatique)
+
+### Slots
+
+- `#header` — contenu du header (titre…). Si absent **et** `showClose=false`, header non rendu.
+- *(défaut)* — corps de la modal (zone scrollable)
+- `#footer` — pied (boutons d'action). Rendu uniquement si le slot est fourni.
+
+## Comportements repris du Drawer
+
+- **Teleport** vers `<body>`.
+- **Focus-trap** : focus initial sur le 1er élément focusable (sinon le panneau) ; boucle
+  Tab / Shift+Tab ; restauration du focus précédent à la fermeture.
+- **Scroll-lock partagé** : compteur module-level (`openModalCount`) — `overflow:hidden` sur
+  `<body>` tant qu'au moins une instance est ouverte, libéré par la dernière (gère aussi
+  `onBeforeUnmount`).
+- **Pattern contrôlé / non-contrôlé** : `isControlled = computed(() => modelValue !== undefined)`
+  avec `localValue` en fallback ; `isRendered` pour démonter après la transition de sortie.
+- **`defineOptions({ name: 'MalioModal', inheritAttrs: false })`** + `v-bind="attrs"` sur le
+  conteneur.
+- **Transition** : fade de l'overlay + fade léger **et scale** (`scale-95 → scale-100`) du
+  panneau (remplace le translate latéral du Drawer).
+
+## Accessibilité
+
+`role="dialog"`, `aria-modal="true"`, `aria-labelledby` vers l'id du header si présent (sinon
+`aria-label`), bouton fermer avec `aria-label="Fermer"`.
+
+## Tests (Vitest + @vue/test-utils, jsdom, colocalisés)
+
+- Rendu conditionnel (fermé → non rendu ; ouvert → panneau + backdrop).
+- `v-model` / contrôlé vs non-contrôlé.
+- Fermeture : croix, backdrop (selon `dismissable`), Échap (selon `closeOnEscape`) ; events
+  `update:modelValue(false)` + `close`.
+- Slots header / défaut / footer (footer rendu seulement si fourni ; header rendu si slot OU
+  `showClose`).
+- Accessibilité : `role`, `aria-modal`, `aria-labelledby`/`aria-label`.
+- Focus-trap : focus initial, boucle Tab/Shift+Tab.
+- Scroll-lock : `overflow:hidden` à l'ouverture, libéré à la fermeture (et avec instances
+  multiples).

+# Design — `MalioTimePicker` (sélecteur d'heure molette, MUI-39)
+
+Date : 2026-05-27
+Branche : `feature/MUI-39-developper-le-composant-select-heure`
+Statut : validé (design), prêt pour plan d'implémentation
+
+## Contexte
+
+`MalioDateTime` a été livré en version intérimaire (MUI-33) avec un `<input type="time">`
+natif sous la grille du calendrier, volontairement isolé dans `DateTime.vue` en attendant
+une maquette pour le sélecteur d'heure dédié. La maquette est maintenant fournie
+(`time.png` à la racine) : c'est une **molette de défilement style iOS** avec bande de
+sélection centrale (pastille teintée), valeur centrée en noir/gras, voisins estompés.
+
+Ce ticket développe ce sélecteur dédié comme **nouveau composant** et rebranche `DateTime`
+dessus.
+
+## Décisions (issues du brainstorming)
+
+| Sujet | Décision |
+|-------|----------|
+| Relation à `MalioTime` (champs texte HH/MM) | **Nouveau composant séparé** ; `MalioTime` reste intact |
+| Nom public | **`MalioTimePicker`** (`time/TimePicker.vue`) |
+| Mécanique | **Molette iOS** : scroll vertical, snap, bande centrale ; valeur centrée = sélection |
+| Colonnes | **2 molettes** : heures `00–23`, minutes `00–59`, pas de **1** |
+| Format `modelValue` | `"HH:MM"` (24h) `string \| null` |
+| Bornes min/max | **Non** (YAGNI) — colonnes pleines |
+| Interaction | **Scroll + clic (recentre) + clavier (↑/↓)** — accessible |
+| Forme | **Champ + popover** (floating-label + icône horloge), comme `Date`/`DateTime` |
+| Style panneau | Même style que le popover date **mais sans `rounded-b`** |
+| Extrémités molette | **Boucle infinie** (23→00 sans fin) |
+| Approche technique | **CSS `scroll-snap` natif** + repositionnement par bloc pour la boucle (zéro dépendance) |
+| Rebranchement `DateTime` | **Dans cette itération** : retrait de l'`<input type="time">` natif |

+
+## Composants & responsabilités
+
+### `TimeWheel.vue` (interne)
+Une colonne molette infinie.
+- **Props** : `modelValue: number`, `values: number[]` (ex. `0..23`), `ariaLabel: string`.
+- **Emits** : `update:modelValue (value: number)`.
+- Délègue scroll/snap/boucle/index-centré au composable `useInfiniteWheel`.
+- Rendu : buffer de valeurs répété ; item centré en noir/gras, voisins estompés (opacité
+  décroissante avec la distance au centre).
+- **Clic** sur un item visible → recentre (`scrollToValue`).
+- **Clavier** : ↑/↓ changent l'index (et scrollent), `role="spinbutton"`, `tabindex=0`,
+  `aria-valuenow` / `aria-valuemin` / `aria-valuemax` / `aria-valuetext`, `aria-label`.
+
+### `TimeWheels.vue` (interne — la brique partagée)
+Compose les 2 molettes + la bande centrale.
+- **Props** : `modelValue: string` (`"HH:MM"`).
+- **Emits** : `update:modelValue (value: string)`.
+- Splitte via `timeFormat` → `heures` + `minutes` ; passe à chaque `TimeWheel` ; recompose
+  et émet à chaque changement.
+- **Bande centrale** : pastille teintée (`bg-m-primary/10` ou équivalent) en overlay
+  positionné au centre, traversant les 2 colonnes ; le « : » séparateur entre les colonnes.
+- **C'est ce bloc qui est inséré dans `DateTime`** (et dans le popover de `TimePicker`).
+
+### `TimePicker.vue` (public `MalioTimePicker`)
+Champ + popover.
+- Input **lecture-seule** affichant `"HH:MM"` (ou placeholder), floating-label, icône
+  `mdi:clock-outline`, bouton **clear** (si `clearable` et rempli).
+- Au clic → ouvre un **popover** au style du popover date **sans `rounded-b`**, contenant
+  `<TimeWheels v-model>`.
+- **Props famille** : `id`, `name`, `label`, `modelValue`, `placeholder`, `required`,
+  `disabled`, `readonly`, `hint`, `error`, `success`, `clearable`, `inputClass`,
+  `labelClass`, `groupClass`.
+- Pattern **contrôlé/non-contrôlé** (`isControlled = computed(() => props.modelValue !== undefined)`).
+- Fermeture au **clic extérieur** (handler local sur le root ; on ne réutilise pas
+  `useCalendarPopover` qui porte une logique `viewMode` propre au calendrier).
+- `disabled`/`readonly` n'ouvrent pas le popover.
+- Ligne `hint`/`error`/`success` + `aria-invalid`/`aria-describedby` comme `CalendarField`.
+
+### `useInfiniteWheel.ts` (composable — cœur logique)
+Toute la mécanique délicate, isolée et testable.
+- **Entrées** : ref du conteneur scrollable, `itemHeight`, longueur des valeurs, valeur
+  courante, callback de changement.
+- **Sorties** : `centeredIndex` (`round(scrollTop / itemHeight) % len`), `scrollToValue(value, smooth)`,
+  handlers `onScroll` / `onScrollEnd` / clavier.
+- **Boucle infinie** : buffer répété N fois ; quand `scrollTop` approche un bord, on
+  repositionne `scrollTop` d'un bloc (hauteur d'un cycle de valeurs) **sans animation**,
+  position visuelle identique → illusion d'infini.
+- Garde anti-boucle entre scroll programmatique et émission `modelValue`.
+
+### `timeFormat.ts` (composable pur)
+- `parseTime(value: string | null): { hours: number; minutes: number } | null`
+- `formatTime(hours: number, minutes: number): string` (zéro-paddé `"HH:MM"`)
+- `padSegment`, `clampHours` (0–23), `clampMinutes` (0–59).
+
+## Flux de données
+
+1. `TimePicker` détient `modelValue` `"HH:MM" | null` (contrôlé/non-contrôlé).
+2. À l'ouverture, `TimeWheels` reçoit la valeur courante ; si **vide**, les molettes se
+   centrent sur un **défaut neutre `00:00` sans émettre**. La **1ʳᵉ interaction**
+   (scroll/clic/clavier) committe et émet.
+3. `TimeWheels` splitte `"HH:MM"` → 2 nombres → `TimeWheel` ; tout changement recompose
+   `"HH:MM"` et remonte via `update:modelValue`.
+4. Le **bouton clear** remet la valeur à vide/`null`.
+5. Le popover **reste ouvert** pendant le réglage (cohérent avec `DateTime`) ; se ferme au
+   clic extérieur.
+
+## Rebranchement `DateTime.vue`
+
+- Remplacer le bloc `<input type="time">` (lignes ~31-41) par :
+  `<TimeWheels :model-value="timeValue || '00:00'" @update:model-value="onTimeChange" />`.
+- `onTimeChange(hhmm)` reprend la logique existante de `onTimeInput` : si `datePart`
+  présent → `composeDateTime(datePart, hhmm)` ; sinon → `pendingTime.value = hhmm`.
+- Supprimer `timeInputId` et le handler `onTimeInput` natif. `pendingTime` / `composeDateTime`
+  / `splitDateTime` inchangés.
+- **Mettre à jour `DateTime.test.ts`** : l'ancien test ciblait `data-test="time-input"` /
+  `type="time"` ; le réécrire pour interagir avec `TimeWheels` (émission de
+  `update:modelValue` depuis la brique).
+
+## Accessibilité
+
+- Molette : `role="spinbutton"`, `tabindex=0`, `aria-label` « Heures » / « Minutes »,
+  `aria-valuenow/valuemin/valuemax/valuetext`, flèches ↑/↓.
+- Champ : `aria-haspopup="dialog"`, `aria-expanded`, popover `role="dialog"`,
+  `aria-invalid` + `aria-describedby` reliés à la ligne hint/error/success.
+- Label lié `for`/`id`.
+
+## Stratégie de tests
+
+- **`useInfiniteWheel.test.ts`** : index centré depuis `scrollTop`, `scrollToValue`, math du
+  repositionnement de boucle (jump par bloc), modulo/clamp.
+- **`TimeWheel.test.ts`** : flèches clavier changent la valeur & émettent, clic recentre,
+  attributs aria (`role`, `aria-valuenow`...).
+- **`TimeWheels.test.ts`** : split/compose `"HH:MM"`, émission de la valeur combinée, 2
+  molettes rendues, séparateur.
+- **`TimePicker.test.ts`** : rendu, label/id, ouverture popover au clic, affichage de
+  `modelValue`, clear, contrôlé/non-contrôlé, `disabled`/`readonly` n'ouvrent pas, aria.
+- **`timeFormat.test.ts`** : parse/format/pad/clamp (valeurs limites, `null`, invalides).
+- **`DateTime.test.ts`** : mis à jour pour la brique molette.
+- ⚠️ **Limite jsdom** : pas de scroll-snap réel. La mécanique est testée via le composable
+  (métriques `scrollTop`/`itemHeight` mockées) ; les tests composant portent sur
+  émissions/clavier/clic/aria, pas le snap pixel.
+- ⚠️ **Tests flaky connus** (Date & InputRichText) : relancer 2–3× avant de conclure à une
+  régression ; hook pre-commit parfois flaky → `--no-verify` documenté.
+
+## Livrables documentation (conventions projet)
+
+- **`COMPONENTS.md`** : ajout `MalioTimePicker` + note « `DateTime` utilise désormais la
+  molette ». (manuel)
+- **`CHANGELOG.md`** : entrée. (manuel)
+- **Playground** : page dédiée + entrée dans `playground.nav.ts` (routage Nuxt centralisé).
+- **Histoire** : `TimePicker.story.vue`.
+- Appui sur la skill `creating-malio-component` pendant l'implémentation.
+
+## Hors scope
+
+- Bornes horaires `min`/`max`.
+- Format 12h / AM-PM.
+- Granularité minutes configurable (`minuteStep`).
+- Colonne secondes.
+
+Ces points pourront faire l'objet d'itérations ultérieures si le besoin métier émerge.
