/* orgo built-in theme: wiki
 *
 * A dense reference site: notes, a personal knowledge base, a manual. Wide and
 * information-first rather than roomy — a table of contents parked in the margin on a
 * large screen, compact headings with visible structure, tables and task lists styled
 * because a wiki is mostly made of them, and org's TODO keywords shown as badges since
 * in a notes site they are content rather than decoration.
 *
 * 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. */
