/* <Big Yikes> design system v4: tactile. Read DESIGN.md (reference lock + decision ledger) before editing.
   Reference lock: Duolingo's product UI owns the component language (buttons on a darker lip that sink when pressed,
   2px outlines with a heavier bottom edge instead of shadows, chunky rounded type, thick progress bars, medal ranks);
   Discord lends headline scale. Big Yikes keeps its own charcoal + yellow, logos, mascots and Valheim art.
   Rules kept from the Figma kit "BY Tactile": one yellow primary action per task area, a selected marker for
   navigation, status always in words, targets >= 44px, 120ms feedback; pressing moves only by transform. */
