 * Matches design-codebase's DragDropQuiz (learn.$stepId.tsx): a "Word bank"
 * card of rounded-full pill tokens above the question, with each blank
 * rendered as its own rounded-full pill. Colors reuse the theme's own
 * --ldal-focus-* tokens (defined in focus-mode.css.j2's :root) instead of

 * literal oklch() fallback on each var() is only for the unlikely case this
