      "notes": "Create a photoreal 2x2 step-by-step beauty transformation grid featuring one young adult woman across four panels with very strong identity consistency. The sequence must read clearly as one continuous at-home hair dye process. Keep the woman visually identical in all panels: same facial structure, same skin tone, same age, same proportions, and same natural beauty direction. Prioritize realism, continuity, and clean anatomy over dramatic complexity. Keep poses simple, believable, and easy to read. Hair transformation must progress logically from dye application to wet post-wash hair, then slightly damp drying stage, then final styled result. The final hair color must be a rich deep auburn-red or dark copper-red with glossy dimensional depth, elegant and luxurious, never bright orange or ginger."
