A previous version of my personal website was scaffolded entirely in HTML and a handful of CSS. I used pandoc as a markdown to HTML converter for blog posts, and wrote a short bash script to package everything up into a bundle of HTML files. GitHub Actions and GH pages were also used like you describe, and then finally I just pointed my domain to the hosted page on GitHub Actions. It worked flawlessly
