I could, but that's a lot of work as well as really overthinking the plumbing. Groff is stuck on HTML4 and XHTML, which means I'd have to stick a sed or awk script on the end of the pipeline. If I'm going to get typesetting involved, it's better to start with an LML & translate that instead.

Two root reasons. First, the server has to be a containerized virtual hypercomputer instead of a basic Web server, limiting hosting options.
Second, JavaScript basically reinventing HTML, which means I have to use an inconveniently expensive browser to download an app every page instead of using CLI tools & a lightning-fast Web browser.
