Panel Hairstyle Lookbook Grid

Create a 12-panel grid (3 columns × 4 rows, numbered 1 to 12) showing the SAME person from the reference photo with 12 different hairstyles. This is a hairstyle lookbook. Final image aspect ratio: 4:5 (vertical/portrait).\nTHE ONLY THING THAT CHANGES BETWEEN PANELS IS THE HAIR ON THE HEAD (shape, style and length only). Everything else stays exactly as in the reference photo.\nIdentity Anchor (Critical)\nThe face must be IDENTICAL to the reference photo in every single panel. Preserve exactly: facial bone structure, jawline, cheekbones, nose shape, lips, eye shape and spacing, eyebrows, skin tone, skin texture (pores, natural imperfections), and overall facial proportions. This is the same real person in all 12 frames. Do NOT beautify, slim, or alter the face. Same age, same expression as in the reference.\nMandatory Rules (Do Not Violate)\n- NO SUNGLASSES. Eyes must be fully visible in all 12 panels.\n- NO ENVIRONMENTAL BACKGROUNDS. Every panel must have a plain, uniform, {argument name="background style" default="solid light grey studio backdrop"} with zero objects, zero textures, zero gradients. Just flat neutral grey.\n- Hair COLOR stays exactly as it appears in the reference photo in all 12 panels. Only the shape, length and style changes, never the color.\nKeep Identical in Every Panel (Do Not Change)\n- MAKEUP AND SKIN: If the person in the reference photo wears makeup, replicate it identically in every panel. Same lip color, same eye makeup, same brow grooming. If they wear no makeup, keep all panels makeup-free. Do NOT add, remove, or alter makeup between panels.\n- Clothing: the same clothing visible in the reference photo, replicated exactly.\n- Accessories: preserve ALL visible accessories from the reference photo (earrings, necklaces, rings, bracelets, piercings, watch, glasses, etc.). Do not omit, resize, recolor, or restyle any accessory. If the person wears prescription glasses (not sunglasses), keep them in every panel.\n- Background: plain solid light grey studio backdrop in every panel. No room, no furniture, no environment.\nThe 12 Hairstyles\n1. Pixie cut: very short, textured, slightly tousled on top with tapered sides and nape\n2.
