/*
 * The documentation site's single stylesheet.
 *
 * The palette is taken from the panel itself (src/app/globals.css): the docs
 * and the application should look alike. The panel is dark by choice; the site
 * follows the system preference, because documentation is read in far more
 * contexts than a server is administered in.
 *
 * No external resource: no font, no script, no CDN. The site works offline and
 * on a GitHub Pages site with no configuration.
