Theming
The docs app uses the local shadcn-svelte configuration in components.json and the global theme in src/lib/styles/app.css. See Styles for the installable token files consumers get.
Published registry items are independent from the docs shell. Put installable component source in registry/items/**, and include any required CSS, dependencies, or registry dependencies in the item frontmatter.
Use semantic tokens such as background, foreground, primary, muted, and border so installed components remain easy to customize. Prefer Tailwind classes like bg-primary and text-muted-foreground over raw color values.
