/* skip-link.css — Skip link. Block: .skip-link
   Markup: first focusable element in <body>: <a class="skip-link" href="#main">Skip to main content</a>,

           corner above sticky headers. Docs-only freeze: .is-focus-visible (shows it in place), .skip-link--preview
           (renders in flow instead of fixed so docs can show it inside a demo card). */
