/* orgo built-in theme: blog
 *
 * A personal site of dated writing. Serif prose at a narrow measure, a masthead rather
 * than a toolbar, and listing pages — the blog index, a tag page, a feed's HTML
 * counterpart — treated as first-class rather than as an afterthought.
 *
 * 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. */
