tokens agents
The system, rendering itself DTCG, three tiers

Every value on this page is a token. So is every value on every other page.

The numbers below aren't a picture of the design. They're the live tokens the site renders with, the same ones, right now. Change one at the root and this page, and every other page, changes with it. No raw hex, no hardcoded pixels, no accent color. The source these compile from is one page over. Read the source

One value, three tiers

The animation on the homepage shows this moving. Here it's held still.

Component Button button.background Same value, in context, rendered.

Icons

Lucide, inline SVG, currentColor

Every icon on this site is one component, five names. Paths are copied verbatim from Lucide (ISC licensed), not hand-drawn, so the shape is exactly the maintained original. No font, so nothing falls back to the platform's system glyph. Default size is 1em, inherited from the surrounding text; the size prop below breaks out to a fixed, token-driven dimension.

The source

This page renders the system. The source page hands it over: the repo, the tokens, and the files agents build against.
