The mini player drew a thin scrubbable progress bar along its top edge on
top of the ambient background fill. Drop the scrub lane: the fill is the
card's only progress display, and precise seeking stays on the
now-playing screen's seek bar. Horizontal drags across the card's top
edge swipe-dismiss the card again.
While music plays, the persistent mini player showed progress only as a
subtle background tint with no way to seek; the full seek bar sat one
navigation hop away on the now-playing screen (#2141).
The card's top edge now hosts a thin visible progress bar inside a taller
touch lane: tap seeks proportionally, dragging scrubs and commits one seek
on release, and hovering or dragging grows the bar and shows a thumb. Card
taps outside the lane still open the now-playing screen. Pointer-only by
design: the overlay never renders on TV and the keyboard focus chain leads
to the now-playing screen's focusable seek bar.
