// `PUT /assets {ids, …}` / `DELETE /assets {ids}`, and having one code path means the selection bar and the
// lightbox's single-asset buttons cannot drift into behaving differently.
//
// Invalidation is broad — the whole ['photos'] key. Favoriting an asset changes the favorites bucket index,
// the timeline tile, the album cover and the asset detail; the queries are cheap and correctness is worth
// more than a surgical cache patch.
