/* The sort and scope switches are the shared cc-tabs `pill` variant
   (cc_tabs.css) — the SAME control as the series hub's Lines/Table/Timeline
   switch, which the Discussion block sits directly under. They used to be a
   grey button group painting its own active state, a second segmented-control
   language in which the idle tabs read as disabled (GH-534). The pill owns the
   skin; these rules only keep the track scrollable for the day a phone cannot
   fit "All / Boards / Catalog discussions" on one line. The 3px inset is what
   keeps the focus ring inside the scroll box, so it is never clipped.
   `width: fit-content` because the parent controls wrapper is a flex column, which
   blockifies the pill's inline-flex and would stretch the track edge to edge. */
