  "portrait_prompt": {
    "subject": {
      "description": "Based on <User Portrait>, extreme close-up selfie, only half of face visible, right hand pressed against right cheek with fingers spread apart, fingers threading through hair, peeking through the gaps between fingers with one visible eye, direct intimate eye contact with camera",
      "features": {
        "hair": "hair, center-parted, falling across left side of face like a curtain, some strands caught between fingers, slightly out of focus at edges",
        "eyes": "One visible right eye with grey-blue colored contact lens, direct gaze into camera, attentive and slightly coy, natural long lashes",
        "expression": "Mouth mostly hidden behind hand, only the side of nose and cheekbone visible, enigmatic and intimate, the hand IS the expression",
        "skin": "Porcelain-cool skin tone, dewy clean texture, natural pores visible up close, no heavy makeup, subtle pink-coral tint on barely visible lips"
      },
      "pose": "Based on user-uploaded pose reference"
    },
    "nails": {
      "color": "Tiffany blue / robin egg blue / mint turquoise — glossy gel finish",
      "shape": "Long almond/oval shape, approximately 1.5cm beyond fingertip",
      "finish": "High-gloss gel polish, smooth reflective surface catching soft light, no matte, no glitter, pure clean color",
      "details": "All five nails same uniform Tiffany blue, clean cuticles, the nail color is THE visual anchor and only saturated color in the entire frame",
      "importance": "CRITICAL — nails must be prominently visible, sharp focus, occupying significant frame space, this is a nail showcase photo"
    },
    "accessories": {
      "ring": "Silver Cartier Love ring (narrow band version) on right ring finger, subtle metallic accent against the Tiffany blue nails"
    },
    "composition": {
      "shot_type": "Extreme close-up (ECU), only half face + one hand visible",
      "focal_length": "50mm (or phone front camera equivalent)",
      "aperture": "f/2.0",
      "camera_angle": "Straight-on selfie angle, very slight upward tilt",
      "camera_height": "Eye-level, arm's length distance (~25cm from face)",
      "framing": "Face and hand fill 95% of frame, ZERO negative space. Left 60%: brown hair curtain as dark mass. Right 40%: skin, eye, nose. Five fingers create diagonal leading lines from upper-left to lower-right, guiding eye to the visible eye. Forehead cropped, chin cropped, left ear cropped — intentionally tight. Hair acts as natural frame/border on left side.",
      "aspect_ratio": "1:1",
      "focus": "Sharp focus on nail surface AND eye in same focal plane, hair edges and background softly out of focus"

    "lighting": {
      "type": "Flat ambient soft light, large diffused source (overcast window or large indoor ambient), completely shadowless on face",
      "direction": "Non-directional, even illumination from front, no side shadow on nose or eye socket",
      "mood": "Clean, flat, bright but not harsh, allows skin texture and nail gloss to read naturally without dramatic lighting interference. Nail surface shows soft material-reflection highlights, not lighting-created specular spots"

      "style": "Fujifilm ASTIA (Soft) inspired color grading, gentle natural skin tones leaning cool porcelain, low contrast, clean whites, the Tiffany blue nails pop as the ONLY saturated color against a near-monochrome palette of skin + brown hair + grey",

      "atmosphere": "Private, intimate, 'I'm showing you something personal up close'"
    },
    "mood": "Intimate, coy, precious, tactile, whisper — 'look at what I got' energy of showing off new nails to someone you're close to, the half-hidden face creates mystery and draws you closer",
