Task: Generate a 4x5 grid layout (20 separate panels) showing a closer view of the subject with 20 different trendy hair colors. Framing Instruction (CRITICAL): - In each of the 20 panels, crop the frame tighter around the subject's face and shoulders (a close-up portrait shot) to emphasize the details of the hair color changes. CRITICAL INSTRUCTION (Style Lock): The original hairstyle structure, length, cut, and texture must remain exactly the same as the source image. Only the color pigmentation should change. Do not alter the physical shape of the hair. Color Selection Criteria (Trendy & Natural Focus): - Randomly apply 20 distinct, highly wearable salon-style colors. - Prioritize Ash & Cool Tones: Heavy emphasis on various shades like Ash Brown, Ash Greige (Grey+Beige), Milk Tea Ash, Cool Platinum, and Smoky Matt. - Include Multi-Tonal Styles: Integrate subtle Two-Tone looks, natural Balayage (sun-kissed streaks), Ombré (darker roots melting into lighter ends), and realistic highlights within the existing hair structure. - Avoid overly artificial neon brights; aim for a chic, sophisticated, and realistic color palette. Constraints: 1. Identity Consistency: Face, makeup, and expression must be 100% identical despite the closer crop. 2. Environment Lock: The visible background and clothing area remain absolutely unchanged. 3. Realism: The coloring must look realistic, preserving original highlights and shadows to define the hair's texture.

Task: Analyze the uploaded image and generate a 4x5 grid (20 panels) of different hairstyles.

Step 1: Facial Analysis Analyze the subject's face shape, facial features, and overall vibe to determine what styles would look best. Step 2: Style Selection (Total 20 Variations)
Panels 1-10 (The "Perfect Match" Collection): Based on your analysis, select 10 unique hairstyles that most beautifully complement the subject's face shape and features. Focus on aesthetics, balance, and modern trends that look naturally flattering.
Panels 11-20 (The "Absurd & Random" Collection): Select 10 hairstyles that are completely unexpected, wacky, or historically/thematically out of place for the subject. Think avant-garde, surreal, or extreme styles that provide a humorous or shocking contrast.
CRITICAL CONSTRAINTS:
Zero-Change Identity: The face, skin texture, eyes, and expression must be 100% identical to the original image in all 20 panels.
Environment Lock: The clothing, lighting, and background must remain exactly the same as the uploaded photo.
Seamless Integration: Ensure the hair interacts realistically with the subject's head and forehead, maintaining high-resolution detail.
Output Format: A high-quality 4x5 contact sheet grid.
