I'm developing a markup language that compiles to HTML and (among other things) allows easily inserting LaTeX equations. Currently they're rendered using KaTeX, which requires custom fonts. Is there a way to make it work without a CDN? I don't want to sacrifice the convenience of being able to quickly write down some math and having it compiled into a single HTML file, so requiring the user to put the fonts somewhere and link them separately is unfortunately not an option.
