## Getting Started

1.  **Install Dependencies**:
    ```bash
    bun install
    ```

2.  **Run Development Server**:
    ```bash
    bun run dev
    ```
    Open [http://localhost:3000](http://localhost:3000) in your browser.

## Configuration
*   **API Proxy**: Requests to `/api/*` are forwarded to the backend (check `next.config.ts` or manually configured in `lib/api.ts` if using direct URL). Currently, `lib/api.ts` points to `http://localhost:5000`.
