Transitions never actually animated: Svelte scopes @keyframes names but does NOT
rewrite animation references in inline style attributes, so the inline
'animation: crossfade-in ...' never matched its scoped keyframe — a hard cut, no fade
(Ken Burns' zoom was dead too). Move the animation into scoped classes and pass dynamic
values via CSS custom properties.
- Real two-layer crossfade: hold the outgoing frame opaque beneath the incoming one
(which is decode-gated), so there's no black flash and no decode pop.
- New slide transitions (from below/left/right) as one reusable component; the previous
frame is pushed off the opposite edge in step (a conveyor/push), easeInOutSine 1s.
- Fullscreen toggle button (Fullscreen API) + 'f' shortcut; Esc in fullscreen no longer
also navigates away.
- Controls now reveal on pointer/keyboard activity and fade when idle (cursor hides too)
instead of being always visible.
- wakelock: null the sentinel on the OS 'release' event so re-acquire-on-visible
actually fires (previously the screen could sleep after the tab was first hidden).

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.

A fullscreen auto-advancing slideshow any user can start. Design:
docs/CONCEPT_DIASHOW.md.
- lib/diashow/queue.ts: SlideQueue state machine — liveQueue drains first
(FIFO, seeded by SSE upload-processed), then shuffleQueue (refilled
from allKnown minus a 5-id ring buffer of recently shown). Pure logic,
unit-testable.
- lib/diashow/wakelock.ts: Screen Wake Lock wrapper that re-acquires on
visibility change (the OS drops the lock when the tab hides).
- lib/diashow/transitions/{index,crossfade,kenburns}.ts: registry +
the v1 transitions. Adding a new animation is one file + one entry —
the extensibility target from docs/FEATURES §2.9.
- routes/diashow/+page.svelte: fullscreen page, hides bottom nav,
6 s default dwell (3/6/10 configurable), keyboard shortcuts
(Escape exits, Space toggles pause), tap-to-reveal overlay with
pause / dwell / transition / exit. Respects $dataMode to choose
preview vs. original URL.
