Detailed JSON-based Image Generation Prompt for Gemini Nano Banana Pro

This is a highly structured, JSON-formatted prompt designed for the Gemini Nano Banana Pro image generation tool. It specifies a complete pipeline sequence for creating an 'Evening Festival Portrait' image, including detailed settings for subject identity preservation (using an attached image buffer), kinematics control (OpenPose), wardrobe assembly, environment staging (Outdoor Night Market), and lighting setup. It's useful for users who want precise control over every aspect of the generated image, especially when starting from a reference photo.
