- Add ISO week numbers to the left of week rows in month view (8, 9, 10...)
with spacer alignment on day-of-week headers
- Inject label + skeleton placeholder lines into fly-rect during zoom animations:
zoom-in shows source label (month name / "Week N" / day name) + pulsing bars
zoom-out shows target context label + skeleton
- Skeleton CSS uses pulse animation (0.8s alternate) for loading hint
- Non-scoped style block for dynamically injected innerHTML elements
- isoWeekNumber helper for ISO 8601 week calculation
- Extended MonthRow type with weekNumber property
