{"portrait_prompt":{"subject":{"description":"Based on <User Portrait>, a young woman sitting alone on a metallic row of connected platform seats at a quiet Japanese JR train station. Body facing LEFT, but head turned back toward the camera in a relaxed 3/4 profile — a calm, unhurried gaze as if just noticed someone calling her name. Expression is serene and contemplative, the quiet confidence of a solo traveler.","features":{"hair":"Long dark hair flowing naturally down shoulders and back, partially tucked under a soft gray knit beret/beanie","eyes":"Calm, present, looking toward camera with gentle awareness — not posing, just acknowledging","expression":"Peaceful and composed — the faintest trace of a soft smile, mostly just quiet contentment. The look of someone comfortable being alone in a beautiful place."
