- Generated 5 outfit texture variants via HSL recolor (saved skin tones) - Dynamic texture_02 swapping when outfit changes - Expression buttons (Normal, Smile, Sad, Angry, Surprised, Blushing) - Random idle expression changes every 8-15s - Responsive canvas sizing with devicePixelRatio support - Outfit generation script in scripts/gen_outfits.py - Smoother lip-sync with phase-based mouth animation
