+            - **Premium Portrait:** 94-96% similarity, excellent balance (recommended)

+            
+            **[ADAPTIVE] Automatic Adjustments:**
+            - Small faces (< 50K px): Boosts identity preservation to 1.8
+            - Low confidence (< 80%): Increases identity control to 0.9
+            - Profile views (> 20° yaw): Enhances preservation to 1.7
+            - Good quality faces: Uses your selected parameters
+            
+            **[PARAMETERS] Parameter Relationships:**
+            - **Strength** (most important): Controls transformation intensity
+              - `0.38-0.45`: Maximum fidelity (Ultra/Subtle presets)
+              - `0.48-0.55`: Balanced quality (Premium/Balanced presets)
+              - `0.58-0.68`: Artistic freedom (Artistic/Style presets)
+            - **Identity Preservation**: Face embedding strength (auto-boosted 1.15x)
+            - **Guidance Scale (CFG)**: LCM-optimized range 1.1-1.5
+            - **LORA Scale**: Pixel art intensity (inverse to identity)
+            
+            **[CONSISTENCY] Consistency Mode Benefits:**
+            - Validates parameter combinations for predictability
+            - Prevents identity-LORA conflicts
+            - Keeps CFG in optimal LCM range
+            - Balances ControlNet scales
+            - Recommended: Always ON
+            
+            **[SEED] Reproducibility:**
+            - **-1:** Random, explore variations
+            - **Fixed (e.g., 42):** Identical results for testing
+            
+            **[WORKFLOW] Recommended Workflow:**
+            1. Upload high-res portrait (face > 30% of frame)
+            2. Select preset (start with Premium Portrait)
+            3. Enable Consistency Mode (ON by default)
+            4. First generation: See quality level
+            5. If adjusting: Change ONE parameter at a time
+            6. Fix seed for consistent testing
+            
+            **[TECHNICAL] System Details:**
+            - Enhanced Resampler: 10 layers, 20 heads, 1280 dim
