Colour theme is configurable at runtime from two seed colours (brand + accent);
neutrals stay fixed for contrast safety. Tailwind v4 var()-based tokens let a
:root:root override recolour everything with no rebuild; the 50->950 ramps are
derived via a color-mix ladder. Config lives in the DB config table (admin UI:
Config > Farbschema, presets + custom pickers + live preview), served on the public
/event endpoint with env defaults (THEME_PRESET/PRIMARY/ACCENT), propagated live via
event-updated SSE, and cached in localStorage for a no-flash boot. The keepsake export
mirrors the same ladder in Rust so offline archives match the event theme.
COMMENTS_ENABLED (env, default true) is a boot-time kill-switch: the backend rejects
new comments with 403 and the frontend hides the comment button (feed card) and
panel/composer (lightbox). Existing comments stay in the DB, hidden, and return when
re-enabled.

Reskin the whole app via design tokens in tailwind-theme.css (remapped
color ramps) plus a define-once component layer in lib/styles/components.css
(.btn, .card, .input, .chip, .badge, .sheet, …). Buttons are muted/outlined
gold rather than flat fills. Self-host Inter + Fraunces (woff2) under the
existing font-src 'self' CSP. Restyle the shared components and the account,
admin, host, join, recover and upload screens against the new tokens.

EventSnap is a client-only SPA: auth is a localStorage JWT and every page fetches its
data in onMount, so SSR only ever produced a logged-out skeleton — including interactive
controls that exist in the DOM before hydration attaches their handlers. Interacting in
that window silently no-ops: a caption typed on /upload never reaches the reactive state
(so cancel() navigates away instead of confirming), and a click on /account's custom
role=radio / leave button does nothing. This surfaced as a ~1-4% mobile e2e flake and is
a real (if brief) bug for users on slow connections too.
Disable SSR app-wide (csr stays on). The server now ships a ~2.5 KB shell with no page
controls, so the pre-hydration window is structurally impossible. No SEO is lost (private,
QR-gated app). app.html paints a themed boot spinner to cover the JS-load gap (script-free;
inline <style> is CSP-safe via style-src 'unsafe-inline'); the root layout's onMount removes
it once the app paints.
Also fixes the one regression ssr=false exposed: /recover's back chevron used
`cameFromApp = from !== null`, which assumes SSR semantics (cold load => from is null). In
CSR mode the initial navigation reports a non-null `from`, sending history.back() to
about:blank. Key on `type !== 'enter'` instead — SvelteKit's initial-load marker in both
SSR and CSR modes.
Verified: desktop 210 passed, mobile 22 passed, back-chevron 10/10, frontend gates green
(svelte-check 0 errors, eslint, prettier, vitest 46).

The frontend had no JS/TS linter — only svelte-check. Add flat-config ESLint (typescript-eslint
+ eslint-plugin-svelte) and Prettier (tabs/single-quote, matching the existing style).
Rules encode "catch bugs, not enforce taste":
- svelte/require-each-key KEPT — it is the exact bug class as the feed mis-tap fix. Fixed every
flagged block: keyed activeFilters, filteredUsers, stagedFiles (by previewUrl), captionTags,
admin tabs/jobs/users, the export-viewer suggestions/filters/comments, and the static skeleton
loops.
- svelte/prefer-svelte-reactivity KEPT — inline-disabled only the verified-safe sites (a local
freq Map in a $derived.by, throwaway URLSearchParams query builders), with a reason each.
- svelte/no-navigation-without-resolve OFF — wants resolve() around every goto()/href; taste, not
a bug, and pure churn.
- svelte/no-unused-svelte-ignore OFF — those comments are consumed by svelte-check, which ESLint
can't see, so it wrongly calls them unused; removing them would reintroduce a11y warnings.
- no-explicit-any OFF for *.test.ts only (partial fixtures legitimately use any).
Real code fixes beyond keys: removed a dead jobLabel(), an unused ViewerComment import and unused
catch binding, an unused scroll-lock arg, and replaced an empty interface with a type alias.
Then `prettier --write` (54 files). Formatting only. Verified: eslint clean, svelte-check 0 errors,
vitest 46 passed, vite build succeeds.

Two items surfaced by the branch re-review:
CSP regression (blocking): script-src 'self' blocked the template-authored
anti-FOUC theme script in app.html — SvelteKit's mode:'auto' only hashes
scripts it injects. Added nonce="%sveltekit.nonce%" so it's substituted per
request and included in the CSP (survives future edits, unlike a pinned hash).
Verified: emitted CSP nonce matches the script tag; no violation, no flash.
feed_delta silent truncation: the LIMIT 200 (added earlier to kill the
stale-`since` DoS) returned only the newest slice with no signal, so a client
that missed 200+ uploads during a reconnect could not tell it should full-
refresh — the older missed uploads were dropped and unrecoverable (the next
delta advances `since` past them). DeltaResponse now carries `truncated`; the
feed's feed-delta handler calls loadFeed(true) to resync from page 1 instead
of merging a partial slice.
Verified: cargo check clean, svelte-check 0 errors, production build green.

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.
