## Run with Docker Compose

```bash
docker compose up --build
```

This starts PostgreSQL and API, runs Prisma generate/db push/seed automatically.

## Auth (JWT in Cookie)

- `POST /api/users/register`
- `POST /api/users/login`
- `GET /api/users/me` (requires cookie)
- `POST /api/users/logout` (requires cookie)

Cookie is HTTP-only and set with `sameSite=lax`.

## Shop endpoints

- `GET /api/health`
- `GET /api/shop/categories`
- `GET /api/shop/products`
- `GET /api/shop/products/:productId`
- `POST /api/shop/products` (`multipart/form-data` is supported, field name: `image`)
- `POST /api/shop/products/:productId/image` (`multipart/form-data`, field name: `image`)
- `POST /api/shop/orders`

Uploaded files are stored in `images/uploads` and are served at `/images/uploads/<filename>`.

Product responses include `image_url` with an absolute URL when an image exists.

Order payload:

```json
{
  "customer_name": "Jane Doe",
  "customer_email": "jane@example.com",
  "items": [
    { "product_id": 1, "quantity": 2 }
  ]
}
```

## Image extraction batch

```bat
scripts\extract-images-from-build.bat "..\build" ".\public\images"
```

Defaults (if arguments omitted):

- Source: `..\build`
- Target: `.\public\images`
