• Zero/positive tilt (warm/dark) → stays on flow (warm body)
Cleaner gain structure:
• srcDeriv = dFlow * radiationDerivGain (derivative gets gain)
• Flow stays as-is (no extra gain needed)
Simpler mixing: Just (1.0 - radiationMix) * flow + (radiationMix * srcDeriv)
This makes more sense because:
• At Tilt 0: Pure flow = warm, full body ✓
• At Tilt -10 (bright): Mix toward derivative, then high-shelf boost = sparkly highs ✓
• At Tilt +10 (dark): Pure flow + low-pass = warm darkening without mud ✓
