The fully-round accent pills + sliding-thumb segments didn't fit. Now every
filter control (kind/sort segments + genre/provider/era chips) shares the
album-detail action-button look: rounded-rect (9px), each tinted from a vibey
8-colour palette that cycles across the row (green/purple/blue/amber/pink/cyan/
coral/violet) — soft fill + border + coloured text, brightening on hover, the
selected one filling with its own colour. Dropped the sliding-thumb segmented
control + its now-dead JS (moveSeg/positionSegs).
