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.
