উল্লম্ব স্তরবিন্যাস সহ উন্নত বাণিজ্যিক খাদ্য/পণ্য পোস্টার টেমপ্লেট

A highly advanced, structured prompt template for Nano Banana Pro (intended for use with Gemini) to create high-end commercial posters for food or products. The prompt uses a 'vertical layered suspension structure' to deconstruct the subject into components (ingredients, structure, final product) and includes detailed instructions for typography, lighting, material texture, and branding elements, all floating against a pure black background.
