/* Full-viewport fixed backdrop. Sits behind the detail content (.mix-detail-foreground is z-index:1)
|
||
and never intercepts pointer events — except the zoom slider, which re-enables them on itself.
|
||
|
||
Footer clip (Phase 10 W1, spec §2c): the backdrop must stop cleanly ABOVE the audio player bar so
|
||
no lava/waveform pixel paints over or under it. `overflow: hidden` clips the canvas to this box, and
|
||
`bottom` is inset by `--player-height`, which AudioPlayerBar publishes on :root via its ResizeObserver
|
||
(Interop/layout/spacer.ts). The observer now points at whichever element is live:
|
||
expanded → the full player dock (tracks breakpoint reflow + error-banner growth)
|
||
minimized → the minimized-dock FAB container (~56–60 px)
|
||
so --player-height is always non-zero while the player is mounted and the clip line follows the bar in
|
||
BOTH states (fix §1 / p10-reframe-w1-fix). The 0px fallback keeps the backdrop full-height on any
|
||
page that does not host the player. */
