   `.nav-toggle-cb:checked ~ .site-nav` then shows the menu.
   Works even when JavaScript is blocked or fails to load
   (CSP, Cloudflare proxies, browser quirks, etc.). The JS
   class `.is-open` is preserved as a parallel mechanism so
   existing JS code continues to work for keyboard escape
   handling and click-outside-to-close.
