- visibleRange action rewritten to scan [data-uid-shell] divs on each
rAF-throttled scroll instead of attaching an IntersectionObserver to
sample tiles. The observer approach broke on return from /inbox: with
cached photo data, shells mounted in the same Svelte pass as the
scroll root and tileRegister fired before any __visibleRange stash
was in place, so registrations dropped silently. Fast scrolling could
also strand the observer in a dead zone when every sample tile left
the viewport before the next was mounted. Shells are always rendered,
so a DOM scan always finds a true first/last.
- Extract PhotoTile + SkeletonGrid so the timeline and the drill-in
PhotoGrid share one tile chrome (selection animation, badges,
hover-only "open preview" affordance).
- FolderTree count badge moves inside the row's button so the badge
area becomes part of the click target instead of a dead zone.
