Feed modes move into tabs in the bar; likes, history, filters and settings,
and account open as one kind of sheet: a drawer on wide screens, a bottom
sheet with a drag handle on phones, with a scrim, Esc, a focus trap and
focus restore.
Cards get an artist avatar, follow and radio pills, a "new" chip, counts
under round action buttons, an up-next pill and a redrawn waveform with
rounded bars, a reflection and the buffered range. The start overlay names
the track behind a big round play button.
New: undo on dislike, a searchable likes list that plays as a queue
(in order or shuffled), a local history of what played, deep links to a
track (?t=handle/slug), a sleep timer, adjustable crossfade, bass boost,
wheel up (w or a long press on the drop) and more keys.
