//   none   → the "lose" slice. Quiet message, no celebration.
//   common → low-value wins (a free spin, a small credit/point payout).
//            Light reveal: prize card pops in, no confetti.
//   rare   → items, badges, or large currency payouts. Full celebration
//            overlay with confetti.
