Core demonstrates a new approach to design system creation. Starting from screenshots of an existing brand identity, Claude analyzes the visual language and generates both a comprehensive design system specification (in Markdown) and an interactive HTML showcase. The result is a fully documented system covering colors, typography, spacing, elevation, icons, and 20+ UI components — all derived from reference material and rendered as a live, browsable interface inside a phone silhouette. The workflow is modular and iterative: as the project evolves, you feed updated references and the design system regenerates — fast, cheap, and consistent.
