/* SEAT HIGHLIGHT REMOVED (operator 2026-08-22): the legacy left/right seat marker highlighted a
   drawer card independent of what's rendered, so a stray card on another row lit up alongside the
   rendered focus row. In the grid model the drawer highlight is driven ONLY by the render-focus
   (.active = the row currently in view), so the seat badge + inset bar are gone. */
