+/**
+ * Live Postgres/MySQL integration tests. These are GATED on env vars so the
+ * normal `bun test` run stays green without a database:
+ *
+ *   WRNEXUS_PG_URL=postgres://…   WRNEXUS_MYSQL_URL=mysql://…   bun test packages/db
+ *
+ * The `bun run test:db:live` script spins up both via docker-compose, sets the
+ * env vars, runs this file, and tears the containers down.
