{
  "subject": {
    "identity": {
      "biometric_reference": "Ana de Armas",
      "facial_structure": "Oval facial morphology with softly defined jawline, delicate mandibular contour, balanced zygomatic arches, subtle cheek fullness, smooth supraorbital ridge and proportionate philtrum depth characteristic of Ana de Armas",
      "dentition": "Natural dental alignment with softly rounded anatomical incisal edges, proportionate central incisors and subtle natural asymmetry typical of Ana de Armas’ smile",
      "iris_pattern": "Highly detailed iris texture with visible crypts and radial furrows, color value #5C6B7A (cool grey-blue tone)",
      "hair_physics": "Voluminous dark brown hair (#3B2F2F) with soft natural waves, fine strand separation, subtle flyaways, and realistic follicular scattering"
    },
    "body": {
      "morphology": "Petite-to-average mesomorphic somatotype, naturally balanced proportions with approximately 0.70–0.72 waist-to-hip ratio, soft natural muscle tone in calves and forearms",
      "skin_physics": "Subsurface scattering (SSS) enabled, visible epidermal pores, subtle natural skin irregularities and faint freckles, no digital smoothing, color value #F1D1C2",
      "extremities": "Anatomically correct five-digit hand structure, natural foot morphology resting on stone, charcoal grey pigmented toenails (#2B2B2B)"
    }
  },
  "wardrobe": {
    "primary_garment": "Matte graphite grey (#3A3A3A) silk charmeuse slip dress, bias-cut, liquid-like surface reflectivity, micro-creasing at the waist",
    "outerwear": "Oversized chunky knit cardigan in deep slate grey (#2F3337), dropped shoulder construction, visible purl stitch texture, tactile wool-blend fiber simulation",
    "accessories": "Thin 925 sterling silver anklet (#C0C0C0) on the right ankle with high specular highlights"
  },
  "pose_action": {
    "stance": "Standing mid-step on the spiral staircase as if slowly descending, body turned slightly sideways along the curve of the stairs",
    "leg_position": "Right foot placed on a lower step while the left foot remains on the upper step, creating a natural walking transition",
    "interaction": "Right hand lightly sliding along the stone railing for balance, left hand gently holding the edge of the cardigan near the waist",
    "head_orientation": "Head turned approximately 25 degrees toward the camera over the shoulder",
    "expression": "Soft, calm expression with subtle curiosity in the gaze"
  },
  "scene": {
    "environment": "Aged neoclassical limestone spiral staircase, weathered balusters with visible mineral deposits and moss growth (#4B5320) in crevices",
    "architecture": "Textured stone steps with erosion patterns, complex geometry of the curving staircase, historical European manor aesthetic",
    "surface_integrity": "Text-free and logo-free surfaces, reflection integrity rules applied to any moist stone patches"
  },
  "lighting": {
    "source": "5500K natural diffused daylight, soft-box effect from overcast sky, high dynamic range (HDR)",
    "physics": "Accurate ambient occlusion in fabric folds and stone crevices, soft specular highlights on silk, realistic shadow casting on the stone steps"
  },
  "camera": {
    "technical_specs": "85mm prime lens, f/2.8 aperture for shallow depth of field, 9:16 vertical aspect ratio, 8k resolution, raw sensor data format",
    "composition": "Full-body vertical frame capturing motion on the staircase, eye-level perspective following the curve of the stairs, sharp focus on facial biometrics with gradual bokeh on the background staircase"
