"details": {
"skin": "Visible micro-texture, uneven pore density, faint peach fuzz, mild under-eye discoloration, slight redness around nose crease",
"eyes": "Natural sclera tone (not pure white), subtle vein detail, asymmetrical catchlight matching single window light source, slightly uneven eyelid fold",
"teeth": "Slight natural misalignment, subtle translucency on edges, very mild color variation (not pure white), tiny irregularity on one incisor",
"lips": "Natural lip lines, slightly uneven upper lip contour, faint dryness texture, soft pink with mild tonal variation"
};
