/* --- Reposition floating panels from the sidebar user block ------------
   NotificationsBell (.notif-panel-wrap) and the sponsor progress popover
   (.sponsor-badge-popover) default to `position: absolute; right: 0;
   top: 100%` — anchored to the button and right-aligned, which fits the
   horizontal navbar but overflows the sidebar. `.vnav-sidebar` has
   `backdrop-filter`, which makes it the containing block for `position:
   fixed` descendants, so these offsets are measured from the sidebar's own
   box: push them just past its right edge instead.
   Desktop-only — on mobile both panels use their own inset:0 full-screen
   modal path, and the bell lives in the top bar rather than here.
   Both offsets derive from `--vnav-w` / `--vnav-w-collapsed`, so changing the
   sidebar width moves them automatically. */
