11 tests for useTimetableKeyboard (RFC v0.2 D20):
- Arrow Left → nudge(-SNAP_MIN, 0, 0)
- Arrow Right → nudge(+SNAP_MIN, 0, 0)
- Shift+Arrow → nudge(±60min)
- Arrow Up/Down → ±lane
- Shift+Arrow Up/Down → ±stage
- ] / [ → cycle stages preserving time + lane
- Enter → openPopover with the selected performance
- Delete → remove with the selected performance
- Space → drag mode + aria-live announce; Arrow keys accumulate; Enter
commits with the cumulative offset; aria-live announces 'bevestigd'
- Esc cancels keyboard drag, no mutation, aria-live announces 'geannuleerd'
- all keys are no-ops when no performance is selected
Tests the composable directly with a host component that owns a focusable
canvas root and exposes the spies + announce ref — much more reliable
than mounting the whole timetable page (heavy + asynchronous).
Test count: 369 → 380.
