TARGETED FIXES FOR SPECIFIC ISSUES
==================================

Based on your debug output, fixing:
1. Wrong hair color detection (dark hair detected as light_blonde)
2. Persistent "Multiple people detected" blocking
3. Prompt length exceeding CLIP token limit

ANALYSIS FROM DEBUG:
- Hair RGB: [159, 145, 134], Brightness: 146.0 → Detected as light_blonde (WRONG!)
- Actual hair: Dark brown/black (visible in source image)
- Issue: Aggressive blonde detection threshold too low
