Guides

Use a closed design-system document to define, validate, compile and apply a brand across Texuli.

[Back to overview](https://texuli.com/solutions/design-systems/)

## The document

A design system is a closed JSON document. The spec defines its shape and validation rules. The tokens package imports, generates, compiles and emits supported formats.

## Apply and govern

Apply compiled values with the Svelte provider or to a host element. Locked documents can declare an allow set for catalog components and their axes.
