Per plan Task 4. onWheel + jumpToScale now animate pos via autoScrub() (drives the same setPos scrub path, ~600ms, lands exactly on the integer + locks). Removes the now-dead advance()/playTransition()/FAST_BLEND_RATE (the server /api/ring/advance round-trip is no longer used by the client). Post-landing morph warm-up folded into setPos's settle branch. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
