Dream-HTML – render HTML, SVG, MathML, Htmx markup from OCaml

A React component "renders" JSX into a page. I think tight definitions no longer apply here.

The word render can be used to describe the process of transforming data into HTML.

In the expected format, it renders (gives or causes to be) a representation of the requested resource.

I think "rasterize" is a better term for what you described.
