What
Coordinate one logical timeline focus target across virtualization, scrolling, selection, and asset interactions.
Why
Focused rows can unmount as the viewport moves; ad-hoc reveal requests caused stale focus and selection races.
How
Replace the older clip-reveal plumbing with one focus coordinator, logical focus state, and bounded render-window retention. Preserve selection when virtualization remounts the target and add focused coordinator/store coverage.
Test plan
Family F tip validation: 200 focused timeline/navigation tests, 3,012 full Studio tests, Studio typecheck, format, lint, file-size gate, and full workspace build.
