High-Fashion Streetwear Editorial (Multi-Panel, Identity Lock)

An extremely complex, structured JSON prompt for Gemini Nano Banana 3, designed for high-fashion editorial image generation. It specifies a multi-panel 2x2 grid layout, strict identity locking based on a reference image, and a focus on extreme wide-angle perspective and foreshortening. It details the model's appearance, specific streetwear wardrobe (neon orange bomber, tactical cargo pants), and technical controls for print-ready quality.
