You can use KaTeX to render mathematical notation.
Abridge automatically detects the katex component in rendered page or section content and loads the KaTeX files only where they are needed.
If you prefer raw $...$ and $$...$$ delimiters, enable the KaTeX auto-render extension with math_auto_render = true. This setting also enables the required KaTeX files.
You are better off using the component rather than the raw $...$ and $$...$$ delimiters because of Markdown processing in Zola. If you look at the examples toward the bottom of the page, notice that the raw-delimiter version ends up with extra commas that do not appear when the same formula is rendered using the component.
