There is a whole slew of classless (semantic) css libraries.

Some examples:

    - https://oxal.org/projects/sakura/
    - https://yegor256.github.io/tacit/
    - https://chimera-demo.vercel.app/
    - https://watercss.kognise.dev/
    - https://missing.style/

Alas, matcha doesn't even look that promising. There is no demo page to quickly see styled elements, the color palette is garish and the default button hover is illegible, with dark background on dark text. It certainly needs more polish.
