The header portals into the shell's FIXED toolbar band, so its height is
list height the user never gets back — and it was spending four stacked
blocks on it: title, meta line, an action row, then a separate view-control
row under the cover. Option B collapses that into two tight rows beside a
smaller cover: title + rename/YouTube-link on the first, with Play-all,
push/revert/delete and the unsynced badge pushed right; the meta line
(count · playtime · filtered) and the view controls (group-by, reset view,
save order, view status, undo/redo) sharing the second.
Every control and its gating is unchanged — the view-control group still
appears only for `items.length > 1 || viewActive`, so a one-item playlist
shows just the meta line.
Measured on a 32-item playlist: the band goes 170px -> 88px at rest
(122px while a view is active, where the status sentence wraps), which is
~80px more visible list.
