An extremely technical and detailed JSON prompt for Nano Banana Pro, focusing on generating an image of Sadie Sink. It includes forensic parameters for identity mapping, highly specific anatomical geometry (emphasizing exaggerated volume and curvature), detailed wardrobe physics (high-tension fabric), and a scene set on a highly reflective industrial stainless steel surface with cinematic studio lighting.
