/* AQcredix — Today's Quiz styles.
 *
 * Every var() carries a hardcoded fallback, and every <button> sets colour and
 * -webkit-appearance explicitly. Both are standing rules on this project: card
 * titles have gone invisible twice when an external stylesheet failed to load
 * and buttons fell back to the default white face.
