Added 3 mystical power-ups that spawn during gameplay:

- **Lotus Align** (cyan) — Auto-nudges rings toward alignment for 3s
- **Time Dilation** (purple) — Slows ring rotation to 30% speed for 5s
- **Harmony Surge** (gold) — 2.5x harmony gain for 4s

Power-ups float near the rings with a bobbing glow effect, fade out before expiring, and show an active timer bar in the top-right corner when collected. Tap them to activate.

**Next Ideas:**
1. **Combo Chains** — Chain multiple power-ups in sequence for score multipliers and cascading particle bursts
2. **Ambient Particle Auras** — Add per-chakra ambient particle rings that orbit the mandala and intensify as harmony rises
