        "Task: Realistic Product Compositing with Material Preservation Goal: Insert the product from Input 2 into Input 1, ensuring placement is logical and lighting interacts accurately with the product's specific material properties.\n\nInput Image(s):\n\nInput 1 (Scene)\nInput 2 (Product): {product_description}\n\nManual Material Breakdown (Critical): To ensure correct light interaction, treat the product as having the following physical properties:\n\nPrimary Material: [e.g., Matte Plastic / Brushed Aluminum / Clear Glass]\n\nReflectivity: [e.g., Low (dull reflections) / High (mirror-like)]\n\nTexture: [e.g., Smooth / Grainy / Porous]\n\nReaction to Light: [e.g., \"Should absorb light with soft highlights, no sharp glares\"]\n\nSecondary Material (if any): [e.g., Gold Foil Label / Glossy Cap]\n\nReaction to Light: [e.g., \"Should catch sharp, bright specular highlights from the environment\"]\n\nProcess:\nScene Analysis: Identify the logical ground plane/surface in Input 1.\n\nPlacement: Scale Input 2 uniformly (maintain aspect ratio) and place it on the surface.\n\nMaterial-Based Relighting:\n\nDo not simply overlay the scene colors onto the product.\nInstead, map the environment light from Input 1 onto the contours of Input 2 based on the material definitions above.\n\nExample: If the material is Matte, only the edge lighting and general ambient tone should change; do not add sharp reflections.\n\nExample: If the material is Glossy, reflect the scene's details on the surface.\n\nShadows: Generate contact shadows that match the hardness/softness of shadows in the rest of the scene.\n\nTechnical Requirements:\nAlbedo Preservation: The intrinsic color of the product (e.g., \"Brand Red\") must not be washed out by the scene's lighting color.\n\nTexture Fidelity: Do not smooth out surface details (grain, bumps) during the blending process.\n\nScaling: No non-uniform stretching.\n\nOutput: A composite where the lighting confirms the materiality of the product (e.g., makes the plastic look like plastic, not metal)."
