+// schema — this just delegates to `prisma migrate deploy`, which applies
+// any pending migrations against DATABASE_URL. Replaces the old
+// src/lib/db.ts's manual `CREATE TABLE IF NOT EXISTS` runner.
+// Requires DATABASE_URL to point at a reachable Postgres (see
+// docker-compose.yml / .env.example).
