  "subject": {
    "identity": {
      "biometric_reference": "Sydney Sweeney",
      "facial_structure": {
        "description": "Heart-shaped face with a soft mandibular line and rounded malar bones. Symmetrical features consistent with the reference identity.",
        "Eyes": "Almond-shaped, clear blue-green (#A3C6C0) with a complex iris pattern and peripheral limbal rings. Gaze is neutral, directed at the lens reflection.",
        "Nose": "Straight dorsum with a refined, slightly upturned tip.",
        "Mouth": "Lips met naturally and softly, occluded (closed) in a relaxed neutral state. Well-defined Cupid's bow with realistic skin texture; zero dental exposure."
      },
      "hair": "Natural Luminous Blonde (#E6D3A0) with high specular reflectivity. Styled in symmetrical double space buns with fine, wispy face-framing strands."
    },
    "body": {
      "morphology": "Ecto-mesomorphic somatotype with a distinct hourglass silhouette and proportional muscle definition. Visible clavicle and suprasternal notch. Skin: Pale, porcelain tone with rosy undertones (#F7E0D3), realistic epidermal pores, and subsurface scattering.",
      "anatomical_integrity": {
        "hands": "Correct five-digit phalangeal structure on the device-holding hand; realistic knuckle anatomy.",
        "feet": "Anatomically complete barefoot structure. Both feet are joined and placed together with ten distinct digits. Toenails feature a crisp white polished finish (#FFFFFF). Zero structural distortions."
      }
    },
    "wardrobe": {
      "garment": "Strapless ruched tube mini dress. Color: Pale carnation pink (#FADADD). Material: High-density elastane-synthetic blend with micro-ribbed textures and directional tension creases.",
      "accessories": "None. The neck and wrists are clear of any jewelry.",
      "Footwear": "Barefoot."
    },
    "pose_action": {
      "description": "Full-body mirror selfie composition. Subject is kneeling on a high-pile silver carpet, torso rotated 15 degrees. Right arm is elevated holding the device; left hand is performing a tactile strand-pull gesture on a loose hair wisp. Facial expression is neutral with the mouth naturally closed."
    },
    "scene": {
      "environment": "Minimalist residential hallway. Walls: Cool-toned slate gray (#B0C4DE). Flooring: High-pile silver carpet (#C0C0C0). Background: White shaker-style door and classic wooden banister. No text or logos on any surface.",
      "composition": "9:16 vertical aspect ratio, centered subject, forensic-grade depth of field."
    },
    "lighting": {
      "source": "Gilded Chiaroscuro directional lighting from a soft golden-hour tungsten source (#FDE4A8) located to the left. This creates dramatic, sculptural shadows and high-contrast highlights that define the subject's form and dress texture.",
      "effect": "Analytical study of form through precise shadow placement. Reflections show 1:1 spatial correspondence with high-fidelity detail."
    },
    "camera": {
      "technical": "35mm prime lens, f/5.6 for sharp analytical focus, ISO 100. 8K resolution, raw sensor output simulation. No digital noise or chromatic aberration."
