The full player previously sat dead-center on wide viewports — cover
+ controls capped at max-w-md left the right two-thirds of the screen
empty while the queue remained behind a drawer toggle. Split the
layout at lg+:
- Extract QueueList from QueueDrawer (header + count + scrollable
list body + empty state); the drawer now wraps QueueList for its
slide-in chrome, and the now-playing route embeds it directly.
- now-playing: at lg+ render the player as a left section + a 384px
(xl: 448px) aside with QueueList. Below lg the layout is unchanged
single-column and the drawer toggle in the bottom row still opens
it (lg:hidden on the toggle button keeps it out of the way once
the panel is permanent).
- QueueList owns the close X conditionally — drawer passes onClose
and the bind:closeButtonRef for focus management; embedded panel
omits both since it has no dismiss action.
QueueTrackRow's drag-to-reorder, click-to-jump, and current-row
highlight all carry over for free since they're owned by the row
component.
