What problem does it solve? Websites and interfaces often end up looking generic or cluttered because they lack a systematic design foundation. This Skill applies universal design principles (golden ratio, type scale, density control) combined with the 21st.dev component library to produce polished, premium-looking sites without hand-rolling every element. ## Core Features & Use Cases - Principle-Based Layout: Applies golden-ratio hierarchy, controlled text/image density, and a named type scale instead of ad-hoc styling. - 21st.dev Component Integration: Pulls interactive components (scroll animations, navbars, cards, footers) from the 21st.dev CLI and re-themes them to project design tokens. - Visual Verification Workflow: Establishes design tokens first, adds Framer Motion last, then screenshots with Playwright to verify the result. - Use Case: When a user asks for a "premium" landing page or says "make it look good," the Skill sets up tokens, lays out with restrained hierarchy, imports 21st.dev components, and visually validates the build. ## Quick Start Ask the agent to design a premium landing page for your product using the art-director approach with 21st.dev components.
