Understand the design system and contribute to it
Component preview
The live preview for UI components is handled by components/atoms/codedocs/ComponentPreview.tsx. Use it directly inside MDX whenever you want a playground-style embed. Provide componentProps to set default values and propOptions to surface toggle-able props next to the preview.
