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).
- Reception also has `identification_number` (auto `N-BR-####`), `merchandise_type`, `merchandise_detail`, `buildings` (M2M), and `pellet_buildings` (via `reception_pellet_building`).
- `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`).
- Global font stack uses Helvetica via Tailwind (`font-sans`) and `frontend/assets/css/main.css`.
- API composable in `frontend/composables/useApi.ts` with `get/post/put/patch/delete` and default JSON/PATCH content types.
- API errors/success toasts can be customized via `toastErrorMessage`/`toastSuccessMessage` or i18n keys `toastErrorKey`/`toastSuccessKey`. Global method fallbacks use `errors.http.*` keys.
- `useApi` uses `useNuxtApp().$i18n` (not `useI18n`) to avoid setup-only constraint in service calls.
- 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`.
- Step 2 uses `frontend/components/reception/reception-product-received.vue` for merchandise selection; type codes in `frontend/utils/constants.ts`.
- 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`).
- Service layer lives in `frontend/services/` with typed DTOs in `frontend/services/dto/`.
- Reception service uses `receptions`, `receptions/{id}`, `receptions/weigh` and supports success/error toast keys.
- Reception receipt endpoint is `receptions/{id}/receipt` (PDF) via `frontend/composables/usePdfPrinter.ts`.

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.
- Nuxt i18n locales live in `frontend/i18n/locales` (configured via `langDir: 'locales'`).
- Default locale is `fr`; translations in `frontend/i18n/locales/fr.json`.

Notes
- Do not add a GET that creates resources; use POST + PATCH.
- Keep endpoints in plural (API Platform convention).
- New reference data added:
  - Reception types (`reception_type`, fields: `label`, `code`), selectable on reception form.
  - Merchandise types (`merchandise_type`, fields: `label`, `code`) and pellet types (`pellet_type`, fields: `label`, `code`).
  - Buildings (`building`, fields: `label`, `code`) and reception allocations (`reception_building` M2M, `reception_pellet_building` unique on reception/pellet/building).
  - Suppliers (`supplier`) with addresses (`address`, fields: `label`, `street`, `postal_code`, `city`, `country_code` ISO2), via `supplier_address` join table.
  - Trucks (`truck`, field: `name`), linked to receptions.
  - Carriers (`carrier`, fields: `name`, nullable `code`), Drivers (`driver`, fields: `name`, `carrier_id`), Vehicles (`vehicle`, fields: `plate`, `carrier_id`, `truck_id`) used for LIOT logic.
  - Reception links: `reception_type_id`, `supplier_id`, `address_id`, `truck_id`, `carrier_id`, `driver_id`, `user_id`.
  - Address exposes `fullAddress` via getter for display.
  - LIOT behavior in reception form: if carrier code = `LIOT`, show driver + vehicle selects and hide manual license plate input; vehicle list filters by truck type and carrier; selected vehicle sets `license_plate`.
