## Notes

- HEAD /api/scenes/:id returned **200** — supported (Next.js returns HEAD for GET handlers by default).
- Final scene version after PATCH sequence: **3** (was 1; bumped to 2 then 3). The name was restored to 'Villa Azul' so downstream verifiers see the original name.
- PUT with stale If-Match "1" returned **409** (expected 409 since version is now 3).
