/**
 * Highlight-to-act affordance (#15844)
 *
 * Every rule here serves the issue's design position — "restraint is the
 * feature" — so the visual weight is deliberately low. This is a small bar
 * beside a selection, not a card competing with the page.
 *
 * Colours come from theme tokens only (no literals), so the affordance follows
 * light/dark with the rest of the site. #15616 shipped near-black text on a
 * dark surface for ~a month because a hardcoded colour was invisible to every
 * gate; Check 92 exists for that class and this file stays inside it.
