/* orgo built-in theme: docs

 * A documentation site: a guide read in order, with a contents block that matters, code
 * blocks that carry as much of the meaning as the prose, and a `#+LEDE:` line under the
 * title. Cooler and more technical than `blog`, narrower and more designed than `wiki`.
 *
 * Every colour is a custom property on :root, so a stylesheet of your own loaded after
 * this one can retheme the site by redefining a handful of values. */
