- Draggable slider bar to scrub through moves like a video
- RTL-aware: drag right = start, drag left = end
- Blue fill + white thumb shows current position
- Touch/pointer events for mobile drag
- Move display text above scrubber shows current move
- Move chips below still clickable as secondary nav
- No more confusing directional arrows
