6    - Okuma mesafesi: 1-2 metre
7    - Z-depth: -0.5m ile +0.5m arası comfort zone
8    
9    🎨 GÖRSEL TASARIM
10    - Glass material kullan (glassBackgroundEffect)
11    - Yüksek kontrast text
12    - Animasyonlar yumuşak (0.3-0.5 saniye)
13    
14    👆 ETKİLEŞİM
15    - Tap, Drag, Rotate, Zoom gesture'ları
16    - Hover feedback (HoverEffectComponent)
17    - Spatial audio ipuçları
18    
19    ⚡️ PERFORMANS
20    - 90 FPS hedefle (her göz için 90Hz)
21    - Model complexity'i düşük tut
22    - Async loading kullan
