This is a really simple KaTeX theme component for Discourse.
It stuffs all the necessary bits at the end of </head>.
It loads all KaTeX and CSS (currently v0.10.0) from the jsdelivr CDN.
It then uses the Discourse theme API api.decorateCooked to update the content of posts.
NOTE: I have deviated from the default KaTeX and use the delimeters $$ for inline LaTeX and $$$ for block LaTeX.
But you can edit the options of the KaTeX function pretty easily from the theme editor.
