Live on this site: the theme name (via useGkTheme), design tokens below (radius, motion, focus, opacity), and density (comfortable vs compact). Changes apply to the documentation preview immediately.
For your app: copy the export at the bottom. It includes createGkKit options plus optional :root CSS overrides. Paste the CSS after import 'god-kit/tokens.css'. Density in production is the gk-density-compact class (see Design tokens), not part of createGkKit.
Not live here: display breakpoints, locale, and component defaults only affect the generated snippet — wire them in your main.ts as shown.
