## Entry Points

- **Frontend**: `frontend/src/main.jsx` - Bootstraps the React application and mounts it to the DOM.
- **Backend**: `app/main.py` - Initializes the FastAPI application, mounts routers, and configures middleware.

## Integration Points

- **API Communication**: The frontend communicates with the backend via REST API calls. Axios is likely used as the HTTP client (from package.json).
- **Database**: The backend connects to the PostgreSQL database container defined in `docker-compose.yml`.
- **Scraping**: The backend connects to the `browserless` service via WebSocket (`ws://browserless:3000`) for Playwright operations.

## Critical Files

- `docker-compose.yml`: Defines the entire stack (App, DB, Browserless).
- `frontend/vite.config.js`: Controls the frontend build process.
- `app/core/config.py` (implied): Likely handles environment variables like `DATABASE_URL`, `OPENAI_API_KEY`.
- `app/models.py`: Defines the data structure (Price, Product, etc.).
