What does this tool practice?

The heart of a design system is deciding values once β€” not per screen β€” by bundling choices like color, spacing, and typography into design tokens and conducting them all from one place. The Composer is a playground where you practice, hands-on, how 27 tokens flow into 13 screen regions at once.

Hover or focus an element in the preview and the tokens that affect it light up in the panel on the right. Trace how far a single value spreads, and connect cause to effect. Your composition is saved automatically in this browser and picks up where you left off next time.
