- Transcript: drag suspends auto-follow; long-press selection suspends following; Latest is a trailing outlined capsule that re-enables follow - Lightwell: pulse via isolated TimelineView (2.4s triangle wave), pauses when offscreen; Reduce Motion uses static geometry (no level resizing) - Increase Contrast: solid Rosewood lightwell fill, 2pt Rosewood selected outlines on mode buttons - Haptics: success only on entering ready, error only on entering failure
