/* Zoom slider — a small viewing control pinned to the top-right, clear of the player bar at

the bottom and the nav bar at the top. It is never a seek surface. top: 5rem sits just below the

fixed nav bar (~4.5rem tall) so neither the expanded player bar nor the nav occludes it.
|
|
|
|
position: fixed (not absolute) because the slider is now a top-level sibling of the backdrop, not
|
|
a child of it — see the comment in the .razor. z-index: 10 lifts it above the page foreground
|

(.mix-detail-foreground, z-index: 1) so the foreground can't intercept its pointer events; that

occlusion was the resolution-slider regression. */
