Poster Design Improvement Prompt (Meta-Prompt)
A meta-prompt or instruction set used to refine and improve a poster design generated by an AI (Nano Banana). The goal is to elevate the design quality from a basic PPT level to something comparable to a one-day design class output. The actual prompt text is referenced externally, but the context describes a prompt engineering process.
