frontend(plumbing): shared theme tokens, cross-cutting stores, gestures, sheets
The plumbing layer the v0.16 UI features (and dark mode) build on.
Shared design tokens (Tailwind v4):
- tailwind-theme.css (new): @custom-variant dark (class-driven, beats OS
default) + @theme color/font/radius tokens + baseline html/html.dark
rules so any page that hasn't been re-themed still renders the right
body bg + color-scheme.
- src/app.css + export-viewer/src/app.css now import the shared theme.
- src/app.html: 6-line FOUC guard sets <html class="dark"> before paint
(mirrored from theme-store.ts) so dark reloads no longer flash white.
Adds <meta name="theme-color"> kept in sync by initTheme().
Cross-cutting stores (one per concern, per docs/FEATURES §2.9):
- data-mode-store.ts: 'saver' | 'original' per-device, plus pickMediaUrl
helper so feed cards / lightbox / diashow all resolve URLs the same way.
- privacy-note-store.ts: hydrated from /me/context, refreshed on SSE
event-updated.
- quota-store.ts: { enabled, used, limit, active_uploaders, free_disk },
refreshed after each upload completes.
- theme-store.ts: 'system' | 'light' | 'dark' preference + derived
appliedTheme + initTheme() that syncs <html class>, localStorage,
and the theme-color meta. Listens to prefers-color-scheme.
- auth.ts: currentPin writable mirror + clearPin() helper called from
the global pin-reset SSE handler — fixes the stale-PIN bug where the
localStorage copy survived a reset.
DTO mirror:
- types.ts: QuotaDto, MeContextDto, PinResetResponse, DeltaResponse each
carry a `// mirrors backend/...` comment per the lib README convention.
SSE client:
- sse.ts: KNOWN_EVENTS registry (one entry per server-emitted type),
synthetic feed-delta dispatched after foreground reconnect via the
/feed/delta?since= endpoint, exponential backoff (1 → 60 s + jitter)
on errors, attempt counter reset on user-initiated visibility resume.
Upload queue:
- upload-queue.ts: IDB schema bumped to v2 — entries tagged with userId;
loadQueue filters by current user (no cross-user leak on shared
devices); uploadItem refuses to upload an entry whose userId differs
from getUserId() (defense-in-depth); new clearQueue() called on
explicit logout. v2 upgrade wipes pre-v2 entries (no userId, can't
attribute safely).
Mobile primitives:
- actions/longpress.ts: 500 ms hold with 10 px move tolerance, swallows
the next click + the right-click contextmenu so the gesture doesn't
double-fire the inner button's onclick.
- actions/doubletap.ts: tap-pair detector that preventDefaults the
second tap so iOS Safari doesn't also zoom on double-tap.
- components/ContextSheet.svelte: generic bottom sheet driven by a
ContextAction[] prop. Reused by feed posts, comments, host user rows.
