className not working for using sass/scss

Hello,

Is it possible to use it? I don't know.

I practice the [documentation](https://github.com/kriasoft/react-static-boilerplate/blob/master/docs/recipes/how-to-use-sass.md) and was successful for build. However, SASS and className (css-modules) could not be used together.

Thank u.

Start with the linked Sass documentation recipe and reproduce the reported case in the starter project. Inspect how Sass styles and CSS-module className usage are configured; the issue is done when both can be used together and the resulting styles apply correctly.
