Generate a complete design system — pattern, style, color palette (with WCAG contrast), typography pairing, effects, anti-patterns, and a pre-delivery checklist — from a product type, industry, and a few style keywords. Runs fully locally from clean-room CSV libraries; no network or paid API required. Trigger when the user says "design system", "generate a design system", "pick colors and fonts for me", "what style fits a [product]", "recommend a palette for [industry]", or "give me the visual language before I build".
