For designers

Start with the characteristics.

Every page in the system is built on the same four-color surface scale, two-family type system, and hairline-everything geometry. Read the principles before you reach for primitives.

For engineers

Two stylesheets. Then build.

Import tokens.css and primitives.css. Use site.cssif you're shipping a marketing surface. Every variable maps directly to production.
