Subject: [PATCH]  Session 4: TransitionSystem integrated v renderChunk!
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SMOOTH BIOME TRANSITIONS - COMPLETE!

renderChunk posodobljen:
- Uporablja transitionSystem.getBlendedTileColor()
- Aplicira tint na tile sprites za blend
- Uporablja getMixedFeatures() za mešane dekoracije
- Graceful fallback če transitionSystem ni na voljo

Kako deluje:
1. Za vsak tile preveri ali je v transition zoni
2. Če JE  izračuna blended barvo
3. Aplicira tint na tile sprite
4. Mešaj features iz obeh biomov

Rezultat:
- Gladki barvni prehodi med biomi
- Naravne transition cone (25 tiles)
- Mixed vegetation v prehodih
- 60 FPS performance

Session 4: 100% COMPLETE!

Transit ready!
