What problem does it solve? Recreating Superhuman's distinctive visual identity in UI work requires knowing exact color values, non-standard font weights, and spacing rules that are hard to guess from screenshots alone. ## Core Features & Use Cases - Complete Design Tokens: Provides exact colors (Mysteria Purple #1b1938, Lavender Glow #cbb7fb, Warm Cream #e9e5dd), typography specs with non-standard weights (460, 540, 600, 700), and a binary 8px/16px border-radius system. - Component Guidance: Covers buttons, cards, forms, navigation, elevation, spacing scale, and responsive breakpoints with do's and don'ts. - Light and Dark Previews: Bundled preview.html and preview-dark.html files show the full token catalog rendered as living style guides for visual verification. - Use Case: When asked to build a landing page styled like Superhuman, generate a hero with the deep purple gradient, 64px headline at weight 540 and 0.96 line-height, and a warm cream CTA button. ## Quick Start Use the Superhuman design skill to create a landing page hero section with the purple gradient and warm cream button.
