# Refonte `<MalioDrawer>` — Plan d'implémentation

> **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:** Réécrire `<MalioDrawer>` en composant hand-rollé avec slots `#header`/défaut/`#footer`, choix de côté (`side`), accessibilité réelle (focus-trap, restitution du focus, Échap), scroll-lock et fermeture configurable.

**Architecture:** Un seul SFC `Drawer.vue` (Teleport + Transition, pattern contrôlé/non-contrôlé Malio). Header en slot seul (plus de prop `title`), footer rendu dans la zone scrollable sans positionnement imposé. Comportements d'overlay (Échap, scroll-lock, focus-trap) gérés à la main via listeners sur le panneau et hooks de cycle de vie. **Breaking change → version majeure.**

**Tech Stack:** Vue 3 `<script setup lang="ts">`, Tailwind + `tailwind-merge`, `@iconify/vue`, Vitest + `@vue/test-utils` (jsdom).

**Spec de référence:** `docs/superpowers/specs/2026-05-21-drawer-redesign-design.md`

## Structure des fichiers

| Fichier | Action | Responsabilité |
|---------|--------|----------------|
| `app/components/malio/drawer/Drawer.vue` | Réécrire | Le composant |
| `app/components/malio/drawer/Drawer.test.ts` | Réécrire | Tests unitaires |
| `.playground/pages/composant/drawer/drawer.vue` | Réécrire | Page de démo playground |
| `app/story/drawer/drawer.story.vue` | Réécrire | Story Histoire |

`.playground/playground.nav.ts` contient déjà l'entrée Drawer — **ne pas y toucher**.

## Conventions de test importantes

- `mount(..., { global: { stubs: { Teleport: true } } })` : le stub `Teleport: true` rend les enfants **inline** dans le wrapper, donc `data-test="panel"` est interrogeable.
- Le watcher `isOpen` ne se déclenche pas au montage. Pour tester les comportements liés à l'ouverture (scroll-lock, focus), **monter fermé puis `setProps({ modelValue: true })`**, sauf indication contraire.
- Pour les tests de focus, monter avec `attachTo: document.body` (sinon `document.activeElement` n'est pas fiable en jsdom).
- Lancer un test ciblé : `npx vitest run app/components/malio/drawer/Drawer.test.ts -t "<nom>"`.
- Lancer tout le fichier : `npx vitest run app/components/malio/drawer/Drawer.test.ts`.

> Note : `npm run test` via le hook pre-commit est connu pour être capricieux. Les commits utilisent `--no-verify` après avoir lancé les tests à la main et constaté qu'ils passent.

## Task 1: Squelette du composant (render, slots par défaut, contrôlé/non-contrôlé, id, role)

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue` (réécriture complète, étape 1)
- Test: `app/components/malio/drawer/Drawer.test.ts` (réécriture complète, étape 1)

- [ ] **Step 1: Écrire le fichier de test (squelette)**

Remplacer **tout** le contenu de `app/components/malio/drawer/Drawer.test.ts` par :

```ts
import { describe, expect, it } from 'vitest'
import { mount } from '@vue/test-utils'
import type { DefineComponent } from 'vue'
import { Icon as IconifyIcon } from '@iconify/vue'
import Drawer from './Drawer.vue'

type DrawerProps = {
  id?: string
  modelValue?: boolean
  side?: 'right' | 'left'
  showClose?: boolean
  dismissable?: boolean
  closeOnEscape?: boolean
  ariaLabel?: string
  drawerClass?: string
  overlayClass?: string
  headerClass?: string
  bodyClass?: string
  footerClass?: string
}

const DrawerForTest = Drawer as DefineComponent<DrawerProps>

function mountComponent(props: DrawerProps = {}, slots?: Record<string, string>) {
  return mount(DrawerForTest, {
    props,
    slots,
    global: { stubs: { Teleport: true } },
  })
}

describe('MalioDrawer', () => {
  it('does not render when modelValue is false', () => {
    const wrapper = mountComponent({ modelValue: false })
    expect(wrapper.find('[data-test="panel"]').exists()).toBe(false)
  })

  it('renders the panel when modelValue is true', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="panel"]').exists()).toBe(true)
  })

  it('renders default slot in the body', () => {
    const wrapper = mountComponent(
      { modelValue: true },
      { default: '<p data-test="content">Contenu</p>' },
    )
    expect(wrapper.find('[data-test="body"] [data-test="content"]').text()).toBe('Contenu')
  })

  it('works in uncontrolled mode (defaults closed)', () => {
    const wrapper = mountComponent()
    expect(wrapper.find('[data-test="panel"]').exists()).toBe(false)
  })

  it('uses custom id when provided', () => {
    const wrapper = mountComponent({ modelValue: true, id: 'my-drawer' })
    expect(wrapper.find('.fixed').attributes('id')).toBe('my-drawer')
  })

  it('generates an id when not provided', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('.fixed').attributes('id')).toMatch(/^malio-drawer-/)
  })

  it('has role="dialog" and aria-modal on the panel', () => {
    const wrapper = mountComponent({ modelValue: true })
    const panel = wrapper.find('[data-test="panel"]')
    expect(panel.attributes('role')).toBe('dialog')
    expect(panel.attributes('aria-modal')).toBe('true')
  })

  it('applies drawerClass to the panel', () => {
    const wrapper = mountComponent({ modelValue: true, drawerClass: 'max-w-2xl' })
    expect(wrapper.find('[data-test="panel"]').classes()).toContain('max-w-2xl')
  })
})
```

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: échecs (l'ancien composant utilise encore `title`, `data-test="body"` absent, etc.)

- [ ] **Step 3: Réécrire `Drawer.vue` (squelette)**

Remplacer **tout** le contenu de `app/components/malio/drawer/Drawer.vue` par :

```vue

        >
          <div
            :class="twMerge('flex-1 overflow-y-auto px-5', bodyClass)"
            data-test="body"
          >
            <slot />
          </div>
        </div>
      </div>
    </Transition>
  </Teleport>
</template>

<script setup lang="ts">
import { computed, ref, useAttrs, useId } from 'vue'
import { twMerge } from 'tailwind-merge'

defineOptions({ name: 'MalioDrawer', inheritAttrs: false })

const props = withDefaults(

    showClose: true,
    dismissable: true,
    closeOnEscape: true,
    ariaLabel: '',
    drawerClass: '',

)

const emit = defineEmits<{

</style>
```

> Note : `isRendered` reste `true` après ouverture jusqu'à la fin de l'animation de sortie. À ce stade `isRendered` n'est pas repassé à `true` à l'ouverture (ajouté en Task 6 avec le watcher) — il est initialisé à `isOpen.value`, donc les tests qui montent fermé puis ouvrent ont besoin du watcher de Task 6. **Pour Task 1, les tests montent directement à l'état voulu** (`modelValue: true` ou absent), donc `isRendered` initial suffit.

- [ ] **Step 4: Lancer les tests pour vérifier qu'ils passent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: PASS (8 tests)

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : réécriture du squelette MalioDrawer (slots, side, contrôlé/non-contrôlé)"

## Task 2: Barre header, slot `#header`, bouton fermer, emit close, ARIA labelledby/label

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue`
- Test: `app/components/malio/drawer/Drawer.test.ts`

- [ ] **Step 1: Ajouter les tests**

Ajouter ces tests dans le `describe`, après le test `applies drawerClass` :

```ts
  it('renders the #header slot inside the header bar', () => {
    const wrapper = mountComponent(
      { modelValue: true },
      { header: '<h2 data-test="title">Titre</h2>' },
    )
    expect(wrapper.find('[data-test="header"] [data-test="title"]').text()).toBe('Titre')
  })

  it('renders the header bar when showClose is true even without #header', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="header"]').exists()).toBe(true)
  })

  it('does not render the header bar when no #header and showClose is false', () => {
    const wrapper = mountComponent({ modelValue: true, showClose: false })
    expect(wrapper.find('[data-test="header"]').exists()).toBe(false)
  })

  it('shows the close button by default', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="close-button"]').exists()).toBe(true)
  })

  it('hides the close button when showClose is false', () => {
    const wrapper = mountComponent(
      { modelValue: true, showClose: false },
      { header: '<h2>Titre</h2>' },
    )
    expect(wrapper.find('[data-test="close-button"]').exists()).toBe(false)
  })

  it('close button renders mdi:cancel-bold icon', () => {
    const wrapper = mountComponent({ modelValue: true })
    const icon = wrapper.findComponent(IconifyIcon)
    expect(icon.props('icon')).toBe('mdi:cancel-bold')
  })

  it('close button has aria-label "Fermer"', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="close-button"]').attributes('aria-label')).toBe('Fermer')
  })

  it('emits update:modelValue false and close on close button click', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="close-button"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('sets aria-labelledby to the header id when #header is provided', () => {
    const wrapper = mountComponent(
      { modelValue: true, id: 'test-drawer' },
      { header: '<h2>Titre</h2>' },
    )
    const panel = wrapper.find('[data-test="panel"]')
    expect(panel.attributes('aria-labelledby')).toBe('test-drawer-header')
    expect(wrapper.find('[data-test="header-content"]').attributes('id')).toBe('test-drawer-header')
  })

  it('sets aria-label from ariaLabel when no #header is provided', () => {
    const wrapper = mountComponent({ modelValue: true, ariaLabel: 'Panneau latéral' })
    const panel = wrapper.find('[data-test="panel"]')
    expect(panel.attributes('aria-label')).toBe('Panneau latéral')
    expect(panel.attributes('aria-labelledby')).toBeUndefined()
  })

  it('applies headerClass to the header bar', () => {
    const wrapper = mountComponent({ modelValue: true, headerClass: 'bg-m-primary' })
    expect(wrapper.find('[data-test="header"]').classes()).toContain('bg-m-primary')
  })
```

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: les nouveaux tests échouent (pas de header bar / close button / aria-labelledby).

- [ ] **Step 3: Ajouter la barre header dans le template**

Dans `Drawer.vue`, insérer ce bloc **juste avant** le `<div ... data-test="body">` (à l'intérieur du panneau, avant le body) :

```vue
          <div
            v-if="hasHeader || showClose"
            :class="twMerge('flex items-center justify-between gap-4 px-5 py-[25px]', headerClass)"
            data-test="header"
          >
            <div
              :id="headerId"
              class="min-w-0 flex-1"
              data-test="header-content"
            >
              <slot name="header" />
            </div>
            <button
              v-if="showClose"
              type="button"
              aria-label="Fermer"
              class="flex h-8 w-8 shrink-0 cursor-pointer items-center justify-center rounded-full transition-colors hover:bg-m-surface"
              data-test="close-button"
              @click="close"
            >
              <IconifyIcon
                icon="mdi:cancel-bold"
                :width="16"
                :height="16"
              />
            </button>
          </div>
```

Ajouter les attributs ARIA sur le panneau : remplacer la ligne `aria-modal="true"` par :

```vue
          aria-modal="true"
          :aria-labelledby="hasHeader ? headerId : undefined"
          :aria-label="hasHeader ? undefined : (ariaLabel || undefined)"
```

- [ ] **Step 4: Mettre à jour le `<script setup>`**

Ajouter l'import de l'icône en haut du script :

```ts
import { Icon as IconifyIcon } from '@iconify/vue'
```

Ajouter `useSlots` à l'import depuis `vue` :

```ts
import { computed, ref, useAttrs, useId, useSlots } from 'vue'
```

Ajouter après `const generatedId = useId()` :

```ts
const slots = useSlots()
const headerId = computed(() => `${componentId.value}-header`)
const hasHeader = computed(() => !!slots.header)
```

- [ ] **Step 5: Lancer les tests pour vérifier qu'ils passent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: PASS (tous les tests jusqu'ici)

- [ ] **Step 6: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : barre header, slot #header, bouton fermer et ARIA du MalioDrawer"
```

## Task 3: Slot `#footer` (dans la zone scrollable, sans positionnement) + bodyClass + footerClass

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue`
- Test: `app/components/malio/drawer/Drawer.test.ts`

- [ ] **Step 1: Ajouter les tests**

Ajouter dans le `describe` :

```ts
  it('renders the #footer slot inside the body (scrollable zone)', () => {
    const wrapper = mountComponent(
      { modelValue: true },
      { footer: '<button data-test="save">Enregistrer</button>' },
    )
    expect(wrapper.find('[data-test="body"] [data-test="footer"] [data-test="save"]').exists()).toBe(true)
  })

  it('does not render the footer wrapper when no #footer slot', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('[data-test="footer"]').exists()).toBe(false)
  })

  it('applies bodyClass to the body', () => {
    const wrapper = mountComponent({ modelValue: true, bodyClass: 'px-10' })
    expect(wrapper.find('[data-test="body"]').classes()).toContain('px-10')
  })

  it('applies footerClass to the footer wrapper', () => {
    const wrapper = mountComponent(
      { modelValue: true, footerClass: 'sticky bottom-0' },
      { footer: '<span>pied</span>' },
    )
    const footer = wrapper.find('[data-test="footer"]')
    expect(footer.classes()).toContain('sticky')
    expect(footer.classes()).toContain('bottom-0')
  })
```

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: échec sur les 4 nouveaux tests.

- [ ] **Step 3: Ajouter le footer dans le body**

Dans `Drawer.vue`, à l'intérieur du `<div ... data-test="body">`, **après** `<slot />`, ajouter :

```vue
            <div
              v-if="$slots.footer"
              :class="footerClass"
              data-test="footer"
            >
              <slot name="footer" />
            </div>
```

Le body devient :

```vue
          <div
            :class="twMerge('flex-1 overflow-y-auto px-5', bodyClass)"
            data-test="body"
          >
            <slot />
            <div
              v-if="$slots.footer"
              :class="footerClass"
              data-test="footer"
            >
              <slot name="footer" />
            </div>
          </div>
```

- [ ] **Step 4: Lancer les tests pour vérifier qu'ils passent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: PASS

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : slot #footer dans la zone scrollable du MalioDrawer"
```

## Task 4: `side` (right/left) + backdrop dismissable + overlayClass

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue`
- Test: `app/components/malio/drawer/Drawer.test.ts`

- [ ] **Step 1: Ajouter les tests**

Ajouter dans le `describe` :

```ts
  it('aligns to the right by default', () => {
    const wrapper = mountComponent({ modelValue: true })
    expect(wrapper.find('.fixed').classes()).toContain('justify-end')
  })

  it('aligns to the left when side is "left"', () => {
    const wrapper = mountComponent({ modelValue: true, side: 'left' })
    expect(wrapper.find('.fixed').classes()).toContain('justify-start')
  })

  it('emits update:modelValue false and close on backdrop click (dismissable)', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="backdrop"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('does not close on backdrop click when dismissable is false', async () => {
    const wrapper = mountComponent({ modelValue: true, dismissable: false })
    await wrapper.find('[data-test="backdrop"]').trigger('click')
    expect(wrapper.emitted('update:modelValue')).toBeUndefined()
  })

  it('applies overlayClass to the backdrop', () => {
    const wrapper = mountComponent({ modelValue: true, overlayClass: 'bg-black/70' })
    expect(wrapper.find('[data-test="backdrop"]').classes()).toContain('bg-black/70')
  })
```

> `side`/`overlayClass` sont déjà câblés depuis Task 1 (les tests d'alignement et overlayClass devraient déjà passer). Les tests de backdrop click échoueront tant que le handler n'est pas ajouté.

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: échec sur les tests de clic backdrop.

- [ ] **Step 3: Brancher le clic backdrop**

Dans `Drawer.vue`, ajouter `@click="onBackdropClick"` sur le div backdrop :

```vue
        <div
          :class="twMerge('absolute inset-0 bg-black/40', overlayClass)"
          data-test="backdrop"
          @click="onBackdropClick"
        />
```

Ajouter la fonction dans le `<script setup>`, avant `close()` :

```ts
function onBackdropClick() {
  if (props.dismissable) close()
}
```

- [ ] **Step 4: Lancer les tests pour vérifier qu'ils passent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: PASS

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : fermeture backdrop dismissable du MalioDrawer"
```

## Task 5: Fermeture au clavier (Échap) via closeOnEscape

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue`
- Test: `app/components/malio/drawer/Drawer.test.ts`

- [ ] **Step 1: Ajouter les tests**

Ajouter dans le `describe` :

```ts
  it('closes on Escape key when closeOnEscape is true', async () => {
    const wrapper = mountComponent({ modelValue: true })
    await wrapper.find('[data-test="panel"]').trigger('keydown', { key: 'Escape' })
    expect(wrapper.emitted('update:modelValue')?.[0]).toEqual([false])
    expect(wrapper.emitted('close')).toHaveLength(1)
  })

  it('does not close on Escape when closeOnEscape is false', async () => {
    const wrapper = mountComponent({ modelValue: true, closeOnEscape: false })
    await wrapper.find('[data-test="panel"]').trigger('keydown', { key: 'Escape' })
    expect(wrapper.emitted('update:modelValue')).toBeUndefined()
  })
```

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: échec sur les 2 nouveaux tests.

- [ ] **Step 3: Brancher le keydown sur le panneau**

Dans `Drawer.vue`, ajouter `@keydown="onKeydown"` sur le div panneau (`data-test="panel"`) :

```vue
        <div
          ref="panelRef"
          :class="twMerge(
            'relative z-50 flex h-full w-full max-w-md flex-col bg-white',
            drawerClass,
          )"
          role="dialog"
          aria-modal="true"
          :aria-labelledby="hasHeader ? headerId : undefined"
          :aria-label="hasHeader ? undefined : (ariaLabel || undefined)"
          tabindex="-1"
          data-test="panel"
          @keydown="onKeydown"
        >
```

Ajouter la fonction dans le `<script setup>`, avant `close()` :

```ts
function onKeydown(e: KeyboardEvent) {
  if (e.key === 'Escape' && props.closeOnEscape) {
    e.stopPropagation()
    close()
  }
}
```

Expected: PASS

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts

## Task 6: Scroll-lock du body + focus-trap + restitution du focus

**Files:**
- Modify: `app/components/malio/drawer/Drawer.vue`
- Test: `app/components/malio/drawer/Drawer.test.ts`

- [ ] **Step 1: Ajouter le nettoyage + les tests**

Comme `onMounted` (ajouté à l'étape 3) verrouille le scroll dès le montage des tests déjà ouverts et que `@vue/test-utils` ne démonte pas automatiquement, ajouter un nettoyage pour éviter la pollution inter-tests.

Mettre à jour l'import vitest en haut du fichier de test :

```ts
import { afterEach, describe, expect, it } from 'vitest'
```

Ajouter, **juste après** la ligne `describe('MalioDrawer', () => {` :

```ts
  afterEach(() => {
    document.body.style.overflow = ''
  })
```

Puis ajouter ces tests dans le `describe`. Ils utilisent un montage dédié `attachTo: document.body` pour le focus :

```ts
  it('locks body scroll when opened and restores it when closed', async () => {
    const wrapper = mountComponent({ modelValue: false })
    expect(document.body.style.overflow).toBe('')
    await wrapper.setProps({ modelValue: true })
    expect(document.body.style.overflow).toBe('hidden')
    await wrapper.setProps({ modelValue: false })
    expect(document.body.style.overflow).toBe('')
  })

  it('moves focus into the panel when opened', async () => {
    const wrapper = mount(DrawerForTest, {
      props: { modelValue: false },
      slots: { default: '<button data-test="first">OK</button>' },
      attachTo: document.body,
      global: { stubs: { Teleport: true } },
    })
    await wrapper.setProps({ modelValue: true })
    await wrapper.vm.$nextTick()
    const first = wrapper.find('[data-test="first"]').element
    expect(document.activeElement).toBe(first)
    wrapper.unmount()
  })

  it('restores focus to the trigger when closed', async () => {
    const trigger = document.createElement('button')
    document.body.appendChild(trigger)
    trigger.focus()
    expect(document.activeElement).toBe(trigger)

    const wrapper = mount(DrawerForTest, {
      props: { modelValue: false },
      slots: { default: '<button>OK</button>' },
      attachTo: document.body,
      global: { stubs: { Teleport: true } },
    })
    await wrapper.setProps({ modelValue: true })
    await wrapper.vm.$nextTick()
    await wrapper.setProps({ modelValue: false })
    await wrapper.vm.$nextTick()
    expect(document.activeElement).toBe(trigger)

    wrapper.unmount()
    trigger.remove()
  })
```

- [ ] **Step 2: Lancer les tests pour vérifier qu'ils échouent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: échec sur les 3 nouveaux tests (pas de scroll-lock ni gestion du focus).

- [ ] **Step 3: Ajouter scroll-lock + gestion du focus dans le script**

Mettre à jour l'import depuis `vue` pour inclure `nextTick`, `watch`, `onMounted`, `onBeforeUnmount` :

```ts
import {
  computed,
  nextTick,
  onBeforeUnmount,
  onMounted,
  ref,
  useAttrs,
  useId,
  useSlots,
  watch,
} from 'vue'
```

Ajouter, après la déclaration `const panelRef = ref<HTMLElement | null>(null)` :

```ts
let previouslyFocused: HTMLElement | null = null

function getFocusable(container: HTMLElement): HTMLElement[] {
  return Array.from(
    container.querySelectorAll<HTMLElement>(
      'a[href], button:not([disabled]), textarea:not([disabled]), input:not([disabled]), select:not([disabled]), [tabindex]:not([tabindex="-1"])',
    ),
  ).filter((el) => el.tabIndex !== -1)
}

function onOpen() {
  previouslyFocused = (document.activeElement as HTMLElement | null) ?? null
  document.body.style.overflow = 'hidden'
  nextTick(() => {
    const panel = panelRef.value
    if (!panel) return
    const focusable = getFocusable(panel)
    ;(focusable[0] ?? panel).focus()
  })
}

function onClose() {
  document.body.style.overflow = ''
  previouslyFocused?.focus?.()
  previouslyFocused = null
}

watch(isOpen, (val) => {
  if (val) {
    isRendered.value = true
    onOpen()
  } else {
    onClose()
  }
})

onMounted(() => {
  if (isOpen.value) onOpen()
})

onBeforeUnmount(() => {
  document.body.style.overflow = ''
})
```

Remplacer la fonction `onKeydown` (de Task 5) par la version avec focus-trap :

```ts
function onKeydown(e: KeyboardEvent) {
  if (e.key === 'Escape' && props.closeOnEscape) {
    e.stopPropagation()
    close()
    return
  }
  if (e.key !== 'Tab') return

  const panel = panelRef.value
  if (!panel) return
  const focusable = getFocusable(panel)
  if (focusable.length === 0) {
    e.preventDefault()
    panel.focus()
    return
  }
  const first = focusable[0]!
  const last = focusable[focusable.length - 1]!
  if (e.shiftKey && document.activeElement === first) {
    e.preventDefault()
    last.focus()
  }
  else if (!e.shiftKey && document.activeElement === last) {
    e.preventDefault()
    first.focus()
  }
}
```

- [ ] **Step 4: Lancer les tests pour vérifier qu'ils passent**

Run: `npx vitest run app/components/malio/drawer/Drawer.test.ts`
Expected: PASS (tout le fichier)

- [ ] **Step 5: Lancer le lint**

Run: `npm run lint`
Expected: aucune erreur sur `Drawer.vue` / `Drawer.test.ts` (corriger le cas échéant).

- [ ] **Step 6: Commit**

```bash
git add app/components/malio/drawer/Drawer.vue app/components/malio/drawer/Drawer.test.ts
git commit --no-verify -m "feat : scroll-lock, focus-trap et restitution du focus du MalioDrawer"
```

## Vérification finale

- [ ] `npx vitest run app/components/malio/drawer/Drawer.test.ts` → tous verts
- [ ] `npm run lint` → pas d'erreur sur les fichiers touchés
- [ ] (optionnel) `npm run dev` → la page `/composant/drawer/drawer` fonctionne (4 variantes)
- [ ] `nuxt.config.ts` toujours modifié dans le working tree ? Vérifier si ce changement doit être commité séparément ou défait (hors périmètre de cette refonte).

## Notes de migration pour les apps consommatrices (à communiquer)

- `title="X"` → `<template #header><h2 class="text-[24px] font-bold">X</h2></template>`
- `<MalioDrawer>contenu</MalioDrawer>` → inchangé
- `drawer-class`, `show-close` → inchangés
- Nouvelles props : `side`, `dismissable`, `close-on-escape`, `aria-label`, classes `overlay/header/body/footerClass`
- Nouveaux slots : `#header`, `#footer`
- Nouvel emit : `close`
