Every token, component, animation, and layout pattern — rendered live. Copy the full system as production-ready markdown for your own projects.
Primitive tokens map to semantic aliases. Use semantic tokens in code — never hard-code hex values.
Four fonts. Strict hierarchy. Monospace signals data and precision. Sans-serif handles prose.
Exact tokens so AI never guesses. Every duration, easing curve, and animation pattern is specified precisely.
| Type | Why AI Fails | Alternative |
|---|---|---|
| Spring physics | AI cannot feel tension/damping — guesses wrong cubic-bezier values | Use Motion MCP /css-spring skill |
| height: auto | CSS cannot transition to auto — AI tries max-height: auto which fails | Use generous fixed max-height or JS measurement |
| 3D transforms | AI gets perspective, rotateX/Y values wrong — produces distortion | Avoid 3D transforms. Specify exact values if needed |
| Layout properties | Animating width/height/margin triggers layout recalculation and jank | ONLY animate transform and opacity |
Every component rendered live. Hover, click, and interact. Each is a direct implementation of the spec.
Hover to see the green top bar reveal and border shift. Every card in the system uses this pattern.
Green border, tinted background, permanent top bar. Used for featured/recommended items.
Grid definitions with responsive breakpoints. Copy the pattern, fill in your content.
