Initializes prefetch on external subtitle track activation, detects
seeks via time-pos delta threshold, pauses prefetch during live
subtitle processing, and restarts on cache invalidation.
- Extract loadSubtitleSourceText into reusable function
- Add prefetch service state and initSubtitlePrefetch helper
- Thread onTimePosUpdate through event actions/bindings/main-deps
- Pause prefetch on subtitle change, resume on emit
- Restart prefetch after tokenization cache invalidation
- Query track-list on media path change to find external subs
Replace createElement('span') with cloneNode(false) from a lazily
initialized template span. Replace innerHTML='' with replaceChildren()
to avoid HTML parser invocation on clear. Add cloneNode/replaceChildren
to FakeElement in tests to support the new APIs.
Collapse applyKnownWordMarking, applyFrequencyMarking, and
applyJlptMarking into a single .map() call. markNPlusOneTargets
remains a separate pass (needs full array with isKnown set).
Eliminates 3 intermediate array allocations and 3 redundant
iterations over the token array.
Detailed TDD implementation plan for 3 optimizations:
- Subtitle prefetching with priority window
- Batched annotation passes
- DOM template pooling via cloneNode
Add isCacheFull() method to controller interface for prefetcher
stopping condition, specify pause flag mechanism for live priority,
and clarify replaceChildren() applies to all subtitle root clears.
Covers three optimizations to minimize subtitle-to-annotation latency:
subtitle prefetching with prioritized sliding window, batched annotation
passes, and DOM template pooling via cloneNode.
- Replace cumulative line chart with activity-focused area chart showing per-interval new words
- Add total words as a blue line on a secondary right Y-axis
- Add pause shaded regions, seek markers, and card mined markers with numeric x-axis for reliable rendering
- Add clickable header logo with proper aspect ratio
- Remove unused "Hide particles & single kana" checkbox from vocabulary tab
5-tab React dashboard with Catppuccin Mocha theme:
- Overview: hero stats, streak calendar, watch time chart, recent sessions

- run the verification in CI and release workflows, and document it in release/docs guidance
- fix docs-site Cloudflare Pages watch path to `docs-site/*` with regression coverage
- show a dedicated startup OSD "building" phase for character dictionary sync
