Wholesale JS -> TS migration of the frontend — stores, utils, actions,
and all Svelte component scripts adopt type annotations. Compile-time
surfaces (app.d.ts, lib/types/) added for shared DTO types.
Build plumbing:
- package.json: dev:frontend script that runs svelte-kit sync first
- tauri.conf.json: beforeDevCommand points at dev:frontend
- run.sh: dropped the sed-hack that temporarily blanked beforeDevCommand;
now relies on npm run dev:frontend to avoid double-Vite
- jsconfig.json: allowImportingTsExtensions
Preserves all Group 1 behaviour:
- page.svelte.ts keeps loadHistory / loadTasks Tauri-first, no
localStorage; saveTranscriptMeta + mapTranscriptRow + mapTaskRow
intact; update_task_cmd and update_transcript_meta_cmd invocations
carry the correct payload shape.
- Toasts, preferences stores typed without behaviour change.
- Viewer still routes segment edits through saveTranscriptMeta; the
Task 1.5 TODO markers are gone.
taskExtractor.ts is functionally improved during the migration:
- multi-task matches in the same sentence
- list-style shopping-verb expansion (get bread, milk, and cheese)

textMeasure.js, virtualList.js, and accessibilityTypography.js were
added in the 2026/04/04 session alongside VirtualSegmentList.svelte but
never committed. All four are imported from DictationPage, HistoryPage,
SettingsPage, and the viewer — a fresh clone had unresolvable imports.
textMeasure.js: pretext-backed text measurement with LRU cache.
measureTextHeight, measurePreWrap, clampTextLines, invalidateCache.
virtualList.js: binary-search visible range for variable-height virtual
lists. buildCumulativeOffsets + findVisibleRange.
accessibilityTypography.js: pretext font/line-height helpers that read
the user's accessibility preference store (Lexend / Atkinson /
OpenDyslexic mapping).
VirtualSegmentList.svelte: virtualised transcript segment renderer used
by the viewer page; depends on all three utils above.
