twind can do server side JIT CSS generation with tailwind style CSS. It would be really cool to add support for that: https://twind.dev/api/modules/twind_sheets.html.

It would require letting the user hook into the render pipeline somehow - they would need to setup twind just before rendering, extract css after the rendering is done, and then inject that into an inline stylesheet. On the client the user would also load twind to dynamically create more classes when components are rendered.
