What it does

Every primitive a fast team needs.

A system styled entirely from the tokens of ${escapeHtml(productName)} — palette, typography, surfaces, and motion. Drop it into any product and it stays in character.

${featureCard('★', 'Tokens that compose', 'Color, type, spacing, and elevation defined once and reused across every surface — from a marketing hero to a row in a table.')} ${featureCard('◐', 'Light & dark in lockstep', 'Every component ships with both modes. The accent reads as confident in either context, and contrast meets WCAG AA out of the box.')} ${featureCard('⌘', 'Desktop-first, but mobile-honest', 'Layouts collapse from a 12-column desktop grid to a focused single column without losing density or rhythm.')} ${featureCard('▣', 'Production-grade primitives', '40+ components — from the obvious (button, input) to the load-bearing (data table, command bar, empty states).')} ${featureCard('↗', 'Designed for handoff', 'Every spec carries a Figma frame, a code snippet, and a "do/don’t" pair so engineers don’t have to guess.')} ${featureCard('∞', 'Built to evolve', 'Tokens version semver-style. A palette refresh ships through one file — no component code touches.')}
In production

A workspace, fully styled.

This is the same component library you'd use in your app — rendered with ${escapeHtml(productName)} tokens.

FAQ

Questions, answered.

${faq('Is this a Figma library, a code library, or both?', 'Both. Tokens flow from one source of truth into Figma styles and into the codegen pipeline at the same time.')} ${faq('Can we ship our own brand theme?', 'Yes — fork the token file, change the palette and type stack, and every component reskins automatically.')} ${faq('What about accessibility?', 'Color contrast meets WCAG AA on every surface. Components ship with focus rings, ARIA roles, and keyboard handling.')} ${faq('How do you handle dark mode?', 'Every token has a paired dark value. The system flips at the document level — no per-component overrides needed.')}
