/* guides.css — styling for Sleipnir guide pages.
 *
 * SELF-SUFFICIENT BY DESIGN. Earlier this file relied on
 * /static/style.css for the footer, but the landing page's footer CSS
 * lives inline in landing.html, not in style.css — so guide footers
 * rendered with raw browser bullets. This file now styles everything
 * the guide template contains (header, article, footer), so guide
 * pages do not depend on style.css being present or carrying any
 * particular rule.
 *
 * All colours use the site's CSS custom properties (defined in the
 * guides_base.html <style> block) so guides track the palette.
 *
 * Ships to /static/guides.css.
