Example with wyw-in-js and linaria

Linaria uses wyw-in-js as its engine. It would be interesting to see an example of its usage. It has plugins for Webpack; can we use them with compatibility? Currently, the new version of MUI (v6) uses pigment-css as a style extractor, which also uses wyw-in-js. With this in mind, it would be interesting to check compatibility with Rspack and Rsbuild, considering that MUI is widely used as a design utility.

I opened an issue on MUI about this matter to check if there is a pigment-css plugin compatible with Rspack.

No specific file, test, or entry point is named; start by reviewing the existing examples in rstack-examples and the linked MUI pigment-css issue. Done would be an example that demonstrates wyw-in-js compatibility with the repository's Rspack or Rsbuild setup, with any compatibility limitations documented.
