## Quick Start (Dev)

### Backend (API)

python -m venv .venv
.venv\Scripts\activate
pip install -r server/requirements.txt
uvicorn server.app.main:app --reload --port 8000
```

### Frontend (Vite)
```powershell
cd frontend
npm install
npm run dev
```

Open `http://localhost:5173`.

## Production

```powershell
cd frontend
npm run build
```

Start the API server; it will serve `frontend/dist` if present:
```
uvicorn server.app.main:app --host 0.0.0.0 --port 8000
```
