Borrow battle-tested visual composition patterns from the Nano Banana Pro prompt library to improve image-generation prompts, Stitch MCP screen/design-system generation, and coded UI design DNA. Use when the user wants to build a hero image, infographic, Bento grid, quote card, product shot, YouTube thumbnail, social-media visual, landing-page mockup, or wants to feed a reference aesthetic into Stitch (`mcp__stitch__*`), Gemini image generation, or a Picasso-style DESIGN.md. Covers 80 curated prompts across 6 UI-relevant categories (featured, infographic, social, thumbnail, product marketing, e-commerce). Activates when the user mentions: "nano banana", "bento grid", "liquid glass", "quote card", "hero image prompt", "thumbnail style", "product mockup prompt", "infographic layout", "Stitch prompt", or asks to generate/improve a UI visual using a reference aesthetic.
