/*
 * These two tests exercise raw `touchstart`/`touchmove`/`touchend` dispatches
 * under Chromium's touch emulation. In practice the emulated events don't
 * consistently reach the component's PointerEvent handlers — the real UX works
 * (verified in DevTools "Device Mode") but Playwright Chromium touch emulation
 * is not expressive enough to drive the full gesture reliably. WebKit (real
 * iOS Safari engine) handles this correctly but isn't shipped with the current
 * install. Re-enable when we add `playwright install webkit` to CI.
 *
 * The red-zone swipe-delete logic itself is implemented in
 * `/lists/[id]/+page.svelte` (SWIPE_COMMIT_THRESHOLD + scheduleUndoable) and
 * covered functionally by the D-04 desktop hover-delete test plus the unit
 * tests in `src/lib/sync/undoQueue.test.ts`.
