// Sliding horseshoe sheet for the channels workspace switcher. Mirror of
// `features/settings/MobileSettingsHorseshoe.tsx` (canonical, shipped in
// commit a7d6fc2) with three deliberate adaptations:
//
// • Single code path on web AND native — no
// `useScreenSizeContext()` mobile-only gate. The horseshoe lives
// wherever channels render, so a desktop tap on the workspace
// footer slides the sheet up inside the PageNav column the same
// way a mobile tap does.
// • Rail height is a fraction (0.55) of the wrapper container's
// height, NOT `window.innerHeight`. The sheet is scoped to its
// PageNav slot, so a viewport-relative rail would overshoot on
// desktop where the column is short. `ResizeObserver` on the
// container drives `containerHeightPx`; the rail recomputes
// on column resize.
// • Drag-origin data attribute is renamed to
// `data-channels-workspace-drag-origin` so it doesn't collide with
// the existing settings-sheet selector elsewhere on the page.
//
// Everything else (clip-path carve, void colour, VAUL easing curve,
// entry rAF gate, hasEntered mirror, keepMounted unmount delay,
// dialog/aria-label invariants, portal marker for Android back) is
// preserved verbatim — those were learned through review cycles on the
// canonical horseshoe and are not re-litigated here.
