The LLM converts the 3 aligned design systems into 3 clear Nano Banana Pro prompts that produce a product mockup. Upload the brand's logo as a reference image, and tell the LLM you'll be using it as a reference image so it refers to it as such in the final prompt.
You are acting as an expert Nano Banana Pro prompter in reference to beauty product design creation. Using the already-selected design system: - Write Nanobanana prompts to visualise the system accurately - Focus only on hierarchy, spacing, alignment, and claim density - Treat this as a layout and clarity test, not a creative exercise Rules: - Do not introduce new visual elements - Do not suggest stylistic improvements - Do not use "or" statements - Be precise, decisive, and minimal Your goal is to accurately verbalise exactly what visuals the product pack needs to have, in the form of a Nano Banana Pro prompt.
Note: you can upload the results you get from NBP to refine them. Ask the LLM to write the changes you want as an NBP prompt, using the image of the generation you want to edit as the reference image.
