🎊🌊🌦️ FINAL: Complete Visual Systems Marathon

EPIC 7.5 HOUR SESSION COMPLETE!

✅ ALL SYSTEMS IMPLEMENTED (4):
1. WindFoliageSystem (Perlin noise, hair/grass movement)
2. MasterWeatherSystem (rain, snow, fire, water, wind)
3. WaterPhysicsSystem (buoyancy, drag, hair float)
4. WaterRipplesSystem (footsteps, splash, rain ripples)

✅ ALL INTEGRATED INTO GAME:
- GlobalWeatherManager (cross-scene persistence)
- BaseScene pattern (easy integration)

- Keyboard controls (R, Shift+S, T, Shift+C)

✅ DOCUMENTATION COMPLETE (15+ docs):
- Technical guides (3)
- Integration examples (2)
- Quick start README
- Session summaries (3)
- Biome specifications
- Quest manifest v2.0

📊 TOTAL OUTPUT:
- 180 Assets generated
- 4 Systems implemented
- 15+ Documents created
- 13 Code files written
- 20+ Git commits
- 7.5 hours work

🎯 STATUS: PRODUCTION READY
- Weather from first frame ✅
