- Synchronized shimmer progression by switching `shimmer.ts` to a shared 2-second phase sweep, with crest/head position interpolated across the full visible span.
- Updated classic and KITT intensity calculations so shimmer starts at index 0 and reaches index length-1 together for any task row length.
- Adjusted shimmer tests to assert crest boundary and phase alignment behavior across short and long strings.
