// On edit, superseded R2/S3 objects are removed by passing orphan descriptors to
// deleteVideoStorage, which derives the bucket keys via collectVideoStorageKeys.
// This guards the descriptors the edit-cleanup builds map to the right keys:
//   - a replaced video entry -> the video key AND its sibling .torrent
//   - a replaced thumbnail entry -> the thumbnail key
// and that only objects under the configured publicBaseUrl are ever collected.
