Add a debounced QuickFilter input at the top of each Library section
to narrow the loaded list without leaving the tab. Server-side
/search remains the route for full-library searches.
- QuickFilter.svelte: 120ms debounced two-way bound input with a
clear button and Escape-to-clear.
- Artists: filter by name; empty-match copy includes a "Search the
full library" link to /search/artists.
- Albums: filter by title + artist_name; same fallback link.
- Liked: filters all three sub-sections (artists/albums/tracks);
sub-section header hides when its filtered length is zero.
- History: filters flatEvents before groupByDay, so day-grouping
reflects the filter.
- Playlists: filters owned + public by name; owners CTA stays.
Covered by QuickFilter unit tests (debounce + clear + Escape).
Add browser tab titles to all 18 static page routes using the pageTitle()
helper from $lib/branding. Titles follow the Minstrel · Section format.

Replaces the explicit 'Load more' button on both library list pages with
an IntersectionObserver-based sentinel that triggers fetchNextPage
automatically as the operator scrolls near the bottom (300px rootMargin).
New InfiniteScrollSentinel component:
- Stays disabled while a fetch is in flight (prevents repeat firing on
tall pages or fast scrolls).
- Tears down its observer when hasNextPage flips false.
- Defensive against environments without IntersectionObserver (jsdom);
tests provide a synchronous mock.
Also fixes a pre-existing test setup gap on the albums page test:
AlbumCard renders LikeButton which calls useQueryClient(), and the
page.test.ts wasn't wrapped in a QueryClientProvider — added the same
useQueryClient mock the AlbumCard.test.ts already uses.
