 "subject": {
 "description": "A young adult woman sitting on a pure white high-key studio floor, wearing a white short-sleeve sporty top, deep navy shorts, white slouch socks, and white sneakers. The image feels like a clean campus-sport portrait while staying grounded in realistic human photography.",
 "mirror_rules": "Not a mirror selfie; do not add a phone, mirror reflection, or selfie traces. Preserve the body direction stretching from the left side of the frame toward the front-right.",
 "age": "young adult, 20-24 years old, explicitly adult",
 "expression": {
 "eyes": {
 "look": "Eyes looking toward the camera, direct but gentle",
 "energy": "clear, slightly curious, with a candid just-caught feeling",
 "direction": "head subtly turned toward the camera, gaze falling through the fringe"
 },
 "mouth": {
 "position": "lips slightly parted, as if breathing or about to speak",
 "energy": "relaxed, soft, not a forced smile"
 },
 "overall": "natural, quiet, mildly intimate, as if captured mid-stretch"
 },
 "face": {
 "preserve_original": "Preserve a soft rounded facial contour, clean fair skin tone, and natural facial proportions; avoid turning the face into an over-retouched influencer look.",
 "makeup": "Makeup direction inspired by East Asian clean campus editorial styling: clean base, soft pink or peach blush, natural lip color, delicate eyeliner, light lashes, almost like naturally healthy skin."
 }
 },
 "hair": {
 "color": "natural black with a subtle cool-toned sheen",
 "style": "low ponytail or low-tied hair, airy straight bangs, loose side strands falling near the cheeks",
 "effect": "smooth but not perfectly arranged, natural highlights on the crown, slightly separated bangs, small real-life irregularities"
 },
 "body": {
 "frame": "slim, natural, lightly athletic, not exaggerated or model-stretched",
 "waist": "waist covered by the loose white top, only slight fabric folds visible from the seated posture",
 "chest": "chest fully covered by the white short-sleeve top, keeping only natural fabric contour without body emphasis",
 "legs": "both legs extended toward the front-right, knees and calves natural, sneaker soles closer to the camera creating slight perspective enlargement",
 "skin": {
 "visible_areas": "Visible skin includes the face, a small part of the neck, ears, upper arms, forearms, backs of the hands, fingers, and most of the thighs from the shorts hem down to above the socks. Shoulders, back, waist, chest, hips, and buttock-adjacent areas are covered or not visually emphasized.",
 "tone": "fair warm ivory skin tone with a slight pink cast, appearing brighter on the arms and legs due to the high-key white lighting",
 "texture": "skin appears fine, soft, clean, and naturally matte, like lightly powdered real skin; it would feel gentle, smooth, and slightly dry rather than glossy or plastic.",
 "lighting_effect": "large soft white light wraps around the exposed skin from the front and above, creating faint overexposed white edges on the arms and upper legs, with very pale gray contact shadows beneath the legs and shoes."
 }
 },
 "pose": {
 "position": "seated on a white floor, body placed toward the left side of the frame, legs extending toward the lower-right",
 "base": "hips grounded, both legs together and straight, toes pointing toward the lower-right, arms extended forward in parallel, palms naturally lowered or close together",
 "overall": "a seated forward-reaching stretch, torso slightly leaning forward, held in a quiet mid-motion moment with slight asymmetry and real body tension"
 },
 "clothing": {
 "top": {
 "type": "short-sleeve sporty polo / campus athletic top",
 "color": "clean white body with deep navy collar and sleeve cuffs",
 "details": "loose short sleeves, soft knit or cotton fabric, natural shoulder drop, slight folds around the hem while seated",
 "effect": "fabric lit by high-key white light, edges softly blending into the white background while keeping real fabric thickness and shadow"
 },
 "bottom": {
 "type": "deep navy athletic shorts",
 "color": "dark blue close to navy",
 "details": "loose shorts, naturally stacked hem, soft folds created by the seated pose",
 "effect": "the dark shorts create the main color contrast against the white space; avoid overly tight or sexualized tailoring"
 }
 },
 "accessories": {},
 "photography": {
 "camera_style": "high-key white studio portrait with a realistic camera feel, close to a fresh Japanese / East Asian campus-sport editorial; not CGI, not overly commercial retouching.",
 "angle": "low camera height close to the floor, lens positioned slightly low at the subject’s front-right, lightly looking down toward the face and extended arms while the sneaker soles become foreground.",
 "shot_type": "full-body seated portrait, 3/4 front-side view, subject concentrated in the lower-left and lower-middle frame, with large blank white space above and to the right.",
 "aspect_ratio": "3:4 vertical portrait",
 "texture": "clean, bright, mildly overexposed, soft highlights, slight real digital-photography texture, not oversharpened.",
 "lighting": "large softbox or white studio bounce light spread evenly from the front, front-left, and above; the background is blown into pure white, leaving only shallow contact shadows below the body.",
 "depth_of_field": "medium depth of field, face and upper body sharp, distant hands and sneaker soles slightly softened but not heavily blurred; likely around a 50mm full-frame equivalent lens at f/4 to f/5.6."

 "elements": [
 "no visible furniture",
 "no props",
 "white floor and white backdrop blending naturally",
 "the original reference has a social-media watermark at the lower-right, but generation should avoid watermarks and text"
 ],
 "atmosphere": "quiet, bright, clean, like a natural frame left between sporty portrait shots",
 "lighting": "the space is filled with white diffuse reflection, shadows are extremely soft, and the spatial boundary is visually reduced"
 },
 "the_vibe": {
 "energy": "light, fresh, quiet",
 "mood": "as if she had just sat down to stretch, is still holding the pose now, and might smile or pull her hands back in the next second",
 "aesthetic": "Japanese / East Asian clean campus-sport editorial, high-key white studio, low saturation, natural realism",
 "authenticity": "keep slight posture offset, loose hair strands, fabric folds, natural finger differences, and realistic wear on the sneaker soles",
 "intimacy": "close but not suggestive, like a photographer quietly capturing a natural resting stretch in the studio",
 "story": "she seems to have just finished a sporty portrait sequence and is stretching on the white floor, leaving a soft trace of breath and movement in the frame.",
