# Design taste skill (Lab micro)

Use only when producing or reviewing UI/HTML cards for hezekai Lab demos.

## Hard rules (must fail a gate if violated)
1. No purple/violet gradient hero backgrounds (`#667eea`, `#764ba2`, `#f093fb`, or `linear-gradient` with those hues).
2. No stock AI marketing copy: "Unlock Your Potential", "cutting-edge", "synergize", "unprecedented value", "Get Started Now".
3. No decorative emoji rows used as visual filler.
4. Prefer one solid near-black CTA on a warm paper background over pill gradient buttons.
5. Title language should match the page audience; Chinese Lab pages use Chinese titles.

## Soft guidance
- Border + paper texture beats glassmorphism for this shelf.
- Keep type scale modest (title ~1.3–1.5rem).
