I agree that React gets overused for many websites, but I'm not sure about this project over something like Astro.

I built an Astro Starter that uses just CSS in a scalable way for simple websites. Content is written in Markdown / MDX files. Design tokens are set in var.css. Other stuff is defined in one config.ts file.

Global styling is set though a few CSS files (Global, Reset, Var, Util, Markdown), components are scoped in styling but utilise the tokens.
