A comprehensive JSON prompt for Nano Banana Pro focused on generating an ultra-photorealistic, candid lifestyle portrait of a man cooking nachos in a modern kitchen at night. The prompt enforces strict identity lock, specifies detailed actions (grating cheese), and focuses on realistic textures like arm hair, skin pores, and the food itself, aiming for a candid handheld phone photo look.
