 * ###### Notes
 *
 * When using `rehype-mathjax/browser`, only `options.tex.displayMath` and
 * `options.tex.inlineMath` are used.
 * That plugin will use the first delimiter pair in those fields to wrap
 * math.
 * Then you need to load MathJax yourself on the client and start it with the
 * same markers.
 * You can pass other options on the client.
 *
 * When using `rehype-mathjax/chtml`, `options.chtml.fontURL` is required.
 * For example:
 *
 * ```js
 * // …
 * .use(rehypeMathjaxChtml, {
 *   chtml: {
 *     fontURL: 'https://cdn.jsdelivr.net/npm/mathjax@3/es5/output/chtml/fonts/woff-v2'
 *   }

 * // …
