Dim the card and decoration while loading. Once data is ready, fade loading out and roll through 3 intermediate digits: 0.6s per digit, 0.12s stagger, ease. Replay even if unchanged.
After the digits settle, show the toast: 0.18s slide / fade in, 2.4s hold, then fade out. On entry, animate the digits without a toast.
