Character Consistency and Hairstyle Collage

Use the provided reference image as the strict identity reference. Create a single 12-image collage featuring the exact same {argument name="subject" default="girl"} in every image. Her facial identity must remain perfectly consistent across all 12 variations. Do not create a different person or reinterpret her appearance. Arrange the result as a clean {argument name="collage layout" default="4×3 professional studio portrait collage"}, with one hairstyle per panel. Keep the same framing, camera angle, pose, expression, clothing, makeup, accessories, background, and lighting in every panel. The only difference between the 12 images should be the hairstyle. Hairstyle variations 1. High ponytail — Sleek high ponytail with a smooth crown and long flowing length. 2. French bob — Jaw-length bob with a soft blunt micro-fringe across the forehead. 3. Long straight middle-part hair — Very long, sleek, pin-straight brown hair falling well below the shoulders, parted in the middle. 4. Shaggy wolf cut — Medium-length heavy layers, choppy fringe, textured volume, and a slightly wild finish. 5. Elegant updo — Polished high chignon with soft face-framing tendrils. 6. Short curly crop — Short, voluminous natural curls with tapered sides and a textured top. 7. Side-swept Hollywood waves — Long glamorous hair with a deep side part and sculpted vintage waves cascading over one shoulder. 8. Sleek low bun — Smooth center-parted hair gathered into a clean, polished low bun at the nape. 9. Long layered waves — Long brown hair with soft cascading layers and natural, loose waves. 10. Shoulder-length blunt cut — Straight, sleek shoulder-length hair with clean blunt ends and a middle part. 11. Curtain bangs — Long natural brown hair with soft curtain bangs framing the face and subtle movement through the lengths. 12. Textured pixie cut — Short modern pixie with textured volume on top, softly tapered sides, and a natural finish. Identity and consistency rules Hair color: Keep exactly the same {argument name="hair color" default="natural brown"} hair color as the reference image. Only change: hair length, hair shape, hair texture, and hair styling. Never change: facial structure, face, eyes, eyebrows, nose, lips, jawline, skin tone, age, makeup, clothing, accessories, pose, expression, or overall identity. The girl must look unmistakably like the same person in all 12 panels. Maintain identical facial proportions and recognizable features throughout the entire collage.
