+
+Project overview
+- Symfony 8 + API Platform 4 backend, Nuxt 3 frontend in `frontend/`.
+- Apache vhost serves API under `/api` and frontend from `frontend/dist`.
+- API base URL on frontend uses `NUXT_PUBLIC_API_BASE` (see `frontend/.env`).
+
+Backend conventions
+- Use English for code identifiers/messages; keep “pont-bascule” as domain term.
+- API Platform operations are defined on Doctrine entities.
+- Reception entity is in `src/Entity/Reception.php`, with custom weigh endpoint `/receptions/weigh`.
+- Reception fields: `date_reception`, `license_plate`, `current_step` (default 0), `is_valid` (default false).
+- `date_reception` is set by the UI, stored as `DateTimeImmutable`, serialized as `Y-m-d`.
+- Weight entity (`src/Entity/Weight.php`) is 1–N with Reception, each row stores `type` (`gross` or `tare`), `dsd`, `weight`, `weighed_at` (all nullable except `type`).
+- Weigh endpoint `/receptions/weigh` returns `PontBasculeReading` with `dsd`, `weight`, `weighedAt` (formatted `Y-m-d`).
+- Custom exception: `App\Exception\PontBasculeException` with French messages, mapped to 500 in provider.
+- Parsing of pont-bascule payload is in `src/Service/PontBasculePayloadDecoder.php`.
+- `config/reference.php` is auto-generated; keep it.
+
+Frontend conventions
+- Nuxt SSR disabled; Tailwind used.
+- Layout in `frontend/layouts/default.vue`: max width `1050px`, header full width.
+- Tailwind custom color palette is `primary` (e.g. `bg-primary-500`).
+- API composable in `frontend/composables/useApi.ts` with `get/post/put/patch/delete` and default JSON/PATCH content types.
+- Pinia store: `frontend/stores/reception.ts` is the source of truth for the current reception.
+- Zod is used for form validation (e.g. `frontend/components/reception/reception-form.vue`); shared helpers live in `frontend/utils/zod-errors.ts`.
+- Weighing logic is shared via `frontend/composables/useWeighing.ts`.
+- Reception step UI uses store state (`currentStep`) in `frontend/pages/reception/[[id]].vue`.
+- Active nav styles in header use `NuxtLink` with `custom` slot.
+- Reusable UI components live under `frontend/components/ui/` and are auto-imported with `Ui` prefix (e.g. `UiLoadingDots`).
+
+Environment & routing
+- Frontend dev server: `npm run dev` in `frontend/`.
+- API base for local dev: `http://localhost:8080/api` (set in `frontend/.env` via `NUXT_PUBLIC_API_BASE`).
+- CORS handled by Nelmio; `.env` includes `CORS_ALLOW_ORIGIN` regex for localhost.
+
+Notes
+- Do not add a GET that creates resources; use POST + PATCH.
+- Keep endpoints in plural (API Platform convention).

 Dans le cas ou le `make start` plante à cause du port de la bdd, il faut modifier **POSTGRES_PORT** dans le fichier .env.docker.local, remplacer le par un port disponible.

+### Configuration global
+Pour les variables d'environnement, il faut demander un .env.local pour le backend et un .env pour le frontend à votre collègue.
