Nano Banana Pro Product Photography Prompt

A highly detailed, structured JSON prompt designed for Nano Banana Pro to generate photorealistic product images. It specifies composition, visual style, lighting effects (prismatic, caustic leaks, amber/cyan gradients), textures (matte metallic, frosted glass), and strict negative constraints to ensure a clean, void-like background without environmental elements or cropping errors.
