Explore "server-side" rendering options

We could get a performance benefit from not-loading all those prismjs mini scripts.

Prismjs supports server-side rendering, see "Usage with Node" section: https://prismjs.com/
We could feed the code through Nashorn or something: https://winterbe.com/posts/2014/04/05/java8-nashorn-tutorial/

Katex also supports it: https://katex.org/docs/api.html#server-side-rendering-or-rendering-to-a-string
