Design Md Specification

Author authoritative, machine-readable DESIGN.md architecture files and YAML frontmatter design token specifications, establishing reproducible visual design systems with mathematical color ramps, concentric container curvature, and tabular alignment.

When to Use

• Establishing a project-wide DESIGN.md document governing UI components and styling tokens
• Codifying design token contracts between UI/UX designers and frontend engineering teams
• Specifying two-tier token architectures (primitives to semantic mappings) in machine-readable YAML
• Defining geometric concentric border radius formulas for complex composite UI cards
• Standardizing OpenType numeric alignments (tabular-nums) and 44px mobile touch target invariants
