- The manga detail desktop overview cover had no reserved aspect-ratio, so
the meta column reflowed when it decoded. Give .cover aspect-ratio: 2/3 +
object-fit: cover (mirrors MangaCard).
- Add decoding="async" to the detail hero/overview covers and the list/shelf
covers (bookmarks, history, continue-reading, collections, tagged rows) so
decode stays off the main thread — previously only MangaCard had it.
