/**
 * THREE CHANCES — component set.
 *
 * Depends on design/tokens.css. Card lives separately in design/card.css.
 * One accent only: gold. Win green and loss red are semantic state colours and
 * are never used decoratively — and never as the sole carrier of meaning, so
 * every win/loss state also ships a glyph or a shape difference.
 *
 * Variants are modifier classes, mapping 1:1 to Figma variants.
