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).

lib/ conventions
Short rules. The patterns we already follow as of v0.16 — write new code that fits.
One store per cross-cutting concern. A single *-store.ts file owns each one:
auth.ts— JWT / PIN inlocalStorage,isAuthenticatedwritableui-store.ts— bottom-nav visibility, upload-sheet open state, FAB badge countdata-mode-store.ts— Saver vs Original media-loading preferenceprivacy-note-store.ts— admin-configured Datenschutzhinweis textquota-store.ts— live per-user storage snapshotupload-queue.ts— IndexedDB-persisted upload queue + processing state
Don't import these into other stores unless strictly necessary; let pages compose them.
DTOs mirror Rust types. All TS interfaces live in types.ts. Each one carries a
// mirrors backend/src/path::TypeName comment so the two stay searchable. If you add
a Rust DTO, add the TS twin in the same PR.
Gestures via Svelte actions in actions/. Long-press, double-tap, future swipe —
each is a use: action that fires a CustomEvent. Components stay free of gesture
plumbing.
Reusable bottom sheets via ContextSheet.svelte. Pass an actions: ContextAction[]
array. Any page that needs a long-press / kebab context menu uses the same primitive.
SSE relays are listed in sse.ts::KNOWN_EVENTS. New server event → add one entry
to that array, that's it.
Diashow transitions live in diashow/transitions/. Each is a Svelte component
plus one entry in transitions/index.ts. Adding a new animation is two-line work; no
diashow code needs to change.
No new global stores beyond the list above unless the new concept is genuinely app-wide. Page state belongs in the page.
