feat(eventsnap): UX review batch-3 — feed virtualization, a11y/UX fixes, shared primitives
Frontend
- Feed: DOM-windowing via @tanstack/svelte-virtual (new VirtualFeed). The window
virtualizer keeps the sticky header, pull-to-refresh, infinite-scroll sentinel and
bottom nav working. List = dynamic measured heights keyed by upload id +
anchorTo:start so an SSE prepend doesn't jump a scrolled reader; grid = measured
square rows. Drops the content-visibility band-aid and the old FeedGrid.
measureElement(null) on row unmount prevents ResizeObserver retention; stable
option callbacks + guarded setOptions avoid O(n) re-measure on like/comment patches.
- Global: viewport-fit=cover (activates safe-area insets), lang=de, PWA manifest +
maskable icon + apple-touch metas, prefers-reduced-motion, safe-area-top headers.
- Feed reactivity: like/comment SSE patch the single card in place; upload-processed
debounced in-place merge; IntersectionObserver leak fixed; shared 60s clock.
- CLS: list cards reserve the skeleton aspect box.
- Destructive actions (promote/demote/unban, gallery release) routed through
ConfirmSheet (host + admin).
- Export OOM: streamed download via single-use ticket instead of res.blob().
- Shared primitives: IconButton (44px hit area), scrollLock action; UploadSheet a11y.
- Polish: api timeout + non-JSON guard, focus-trap offsetParent fix, pull-to-refresh
passive:false + guards, diashow keyboard a11y, Toaster assertive errors, dark-mode
gaps, aria-pressed on like/chip state, CameraCapture mic-on-video + retry,
ConfirmSheet spinner, upload beforeunload warning, emoji->SVG icons.
Backend
- social.rs: like/comment SSE broadcasts now carry the fresh count so feed clients
patch one card in place instead of refetching page 1.
- admin.rs / main.rs: supporting changes for the above.
Verified: svelte-check 0 errors, frontend build clean, /feed SSR 200. Runtime feed
scroll-feel validation still owed (documented in FOLLOWUPS.md).
