Preference 172: no "Load more" buttons. Eight remained, on Liked (three
sections), the three Search overflow pages, Genres and Years.
- ListContinuation: the one bottom-of-list block. It loads the next page
ahead of the reader, announces "Loading more…" through aria-live, shows an
optional end line, and on a failed page shows the error with Try again,
dropping the sentinel so a dead endpoint isn't re-hit on every scroll.
Used on all ten paged lists, including the four that already autoloaded.
- A failed next page no longer replaces the list. TanStack sets isError for
it, so the page-level error branches now apply only to a failed first
load. Genres and Years did the same with their own loader; a later
page's failure now keeps the grid.
- Liked: Artists | Albums | Tracks tabs (operator's choice). Stacked, a
long Artists list loading as you scroll would bury the other two. It
opens on the first tab that has likes.
- TabStrip: the in-page tab strip, now shared by Liked, Playback errors
and Requests.
- test-utils/intersectionObserver: a stand-in so tests can scroll to the end.
