 - **Dockerfile**: Multi-stage — `oven/bun:1` (build + compile) → `gcr.io/distroless/cc-debian13:nonroot` (runtime)
 - **Runtime**: Bun-compiled standalone binary (glibc-linked, requires `cc` distroless variant)
-- **Compose**: `app` (port 3000) + `postgres:17-alpine` (port 5432) with health check
-- **Migrations**: Run separately — `bun run db:push` (dev) or `bun run db:migrate` (prod) against the compose DB
+- **Compose**: `app` + `db` with health check dependency
+- **Migrations**: Nitro plugin runs `migrate()` at server startup (see `src/server/plugins/migrate.ts`)
 - **Env**: `DATABASE_URL` set in `compose.yaml` pointing to the `db` service
