Anonymous stats endpoints (`/api/statistics-all`, `/api/statistics-today` for today's top songs, `/api/users`); radio-source CRUD and token validation require authorization.

The song/user dashboards support search, sortable columns, pagination (`Pagination`/`SortableTh` components, 10 rows per page), an all-time/today filter (songs), relative "last played" timestamps (`utils/time.ts`), and auto-refresh every 60s via TanStack Query `refetchInterval`. Charts adapt to mobile via the `useIsMobile` hook. The API base URL is relative (`/api`) in production builds because the Worker serves the SPA and API from the same origin (works for local docker and deployment alike); only `.env.development` points at `http://localhost:5000/api` for the Vite dev server. Build output writes into `src/Worker/wwwroot/`, which is served by the Worker as static files with SPA fallback to `index.html`.

The API base URL is hardcoded in `services/api.ts`: relative `/api` for builds (the Worker serves the SPA and API from the same origin, so this works for local docker and deployment alike) and `http://localhost:5000/api` only when `import.meta.env.DEV` is true (the Vite dev server). Do NOT reintroduce `VITE_API_BASE_URL` env files: bun auto-loads `.env*` into `process.env`, which outranks `.env.production` in Vite and once leaked the dev URL into a deployed production build. Note that `deployment/docker-compose.override.yml` (VS debug tooling) sets `BUILD_CONFIGURATION: Debug` and a `--wait-for-debugger` entrypoint; it is auto-applied if you run `docker compose` from `deployment/` without `-f`, so always use the explicit `-f deployment/docker-compose.yml` form for real runs. Build output writes into `src/Worker/wwwroot/`, which is served by the Worker as static files with SPA fallback to `index.html`.
 - **Worker** (`src/Worker/`) - Composition root. Program.cs builds a `WebApplication` that hosts the NetCord Discord gateway (registered via `AddDiscordGateway`), the ASP.NET Core web API, and the `GuildPlayerManager` hosted service in one process on port 5000.
