ai-design-workflow 是做什么的？
Three-stage Discover, Define, Deliver workflow for getting distinctive, studio-grade UI design out of an AI coding agent instead of the default "AI template" look. Use whenever the user asks to design or redesign a landing page, marketing page, app screen, onboarding flow, dashboard, poster-like web page, or game UI and wants it to look original, bold, premium, or "not like AI made it", including phrases like "make it unique", "it looks generic", "too much AI vibe", "AI 味太重", "千篇一律", "设计得独特一点", "榨出创造力", "design critic", "critique loop", "seed string", "double diamond", or "why does my AI design always look the same". Also use when iterating on an existing page whose layout is the stock hero-left/illustration-right template, or when the user wants image or video generation woven into a UI. Covers seed-string randomness, ambitious briefs, a screenshot-only design-critic subagent loop, image/video-driven motion, and the final subtraction pass.
