/* CoinParty — motion (step 4).
 *
 * The house gesture is paper, not glow: cards lift and their hard shadow grows,
 * confetti snips fall, ribbons unfurl. Everything here is decorative and every
 * rule is switched off under prefers-reduced-motion at the end of the file
 * (base.css carries a global guard as well — this file keeps its own so it can
 * be read on its own terms).
