 For local Docker, host port mapping comes from `docker-compose.override.yml` (default `http://localhost:3000`, configurable via `APP_PORT`).
-The local override also starts PostgreSQL and wires `DATABASE_URL` to `postgres://postgres:postgres@postgres:5432/fiscal_clone`.
-For Coolify/remote Docker Compose, only container port `3000` is exposed internally (no fixed host port bind), avoiding host port collisions.
+The base Docker Compose now includes an internal PostgreSQL service (`postgres`) used by Better Auth by default.
+For Coolify/remote Docker Compose, only app container port `3000` is exposed internally (no fixed host port bind), avoiding host port collisions.
+If you use an external Postgres instance, set `DATABASE_URL` explicitly.
 Runtime data persists in the `app_data` volume (`/app/data` in container).
 Docker builds install the npm version from `NPM_VERSION` (default `latest`).
