Detailed JSON-structured image generation prompt for a relaxed luxury portrait

A highly detailed, JSON-structured prompt designed for image generation models (like Gemini Nano Banana Pro) to create a relaxed luxury travel photo. It specifies the subject's appearance, outfit, pose, location (a rooftop terrace overlooking the Monaco harbor circuit), lighting, composition, and even typography details for a realistic, low-contrast portrait.
