- Mouse/browser Back button now behaves like Backspace/Esc: while a
menu, the shortcuts sheet, the info overlay or an auto-skip countdown
is up, Back closes/cancels that (via a history entry) instead of
dropping straight to the grid; with nothing open it still leaves.
- Whole player UI is 25% larger for lean-back/HTPC legibility, applied
as transform: scale(1.25) on an 80vw x 80vh root (fills the viewport
exactly). transform, not zoom — under zoom, event clientX and
getBoundingClientRect fall into different spaces and the seek/volume/
hover math breaks; transform keeps them aligned. Skip buttons ride
this scale (reverted their separate enlargement so they're +25% too).
- Seek bar: drag the head to scrub, not just click-to-jump; the head
previews the target and the seek commits on release (pointer capture),
so a long drag doesn't restart the stream on every step.
- Volume bar: dropped the loudness gradient — back to the plain accent
fill; the 0-100 hover value tooltip stays.
- Harden both bars' pointer-capture calls (try/catch) so a capture
failure can't abort the click/drag.
