Hey [@jrgarciadev](https://github.com/jrgarciadev), createThemeBase() used default className(`${type}-theme`) in `stitches.config.ts`, so [useEffect in ThemeProvider](https://github.com/nextui-org/nextui/blob/10c4c25bfd39b02987631a4a888ef820710a8c8d/packages/react/src/theme/theme-provider.tsx#L84) will changeTheme(userTheme.className);
