 - Нарезка через API `POST /tiles/slice` или вызов сервиса `TileService.slice_to_tiles` (внутри backend).
 - Поддерживаются входы, которые понимает GDAL (GeoTIFF, JPEG, MBTiles и др.). Нарезка идёт в профиле Web Mercator (XYZ) по умолчанию.
 
+## Фронтенд
+- В `frontend` лежит Tauri/React приложение для проверки бекенда (карта Leaflet, WebSocket трек, форма для запуска нарезки тайлов).
+- Запуск: `cd frontend && pnpm install && pnpm dev` (или `pnpm tauri dev` при установленном Rust/Tauri). Бекенд должен слушать `http://localhost:8000`.
+
 ## Ключевые зависимости
 - fastapi — REST и WebSocket
 - uvicorn[standard] — ASGI-сервер
