User report: the round dot didn't read as vertically centered on the 4dp track even though geometrically it was (M3's SliderLayout centers the track slot within the thumb's height). A small circle on a thin horizontal bar is a known perceptual offset — the eye expects the bar to bisect the circle, but the circle's mass extends above and below in equal amounts the brain reads as a lift. Swap the 14dp circle for a 4dp x 18dp vertical pill (CircleShape on a non-square Box renders as a stadium). Same width as the track, clearly taller — the bar visibly passes through the pill's horizontal axis with no ambiguity. Also aligns with M3 expressive's new vertical-handle slider direction. Updates the ScrubTrack docstring that still referenced the prior 14dp-on-4dp pairing.
