/* Header-row pinning. Two CSS paths, picked by `header-pin/controller.ts`:
   - native sticky (preferred): wrapper drops its overflow constraint so
     `position: sticky` on the row can resolve against the document scroll.
   - transform fallback: wrapper keeps `overflow-x: auto` for horizontal
     scrolling; the row is positioned imperatively per scroll frame.

   `--editor-pin-offset` is published to :root by `pinOffsetWatcher` in
   `header-pin/offset.ts`, measured against the lowest fixed surface above
   the editor (app shell header, page header, fixed toolbar). */
