/* riddler-quiz.css
 * Cleaner quiz UI: question cards with shadow, answer options as cards,
 * clear CTA navigation buttons. Includes Dark Mode.
 *
 * UPDATE (mobile compact):
 * - On small screens, multiple-choice grids force two columns.
 * - Tighter spacing (gap/padding) and slightly smaller text to reduce scrolling.
