/* The small rounded-rectangle buttons shared by the website's pages and
   Connect: the back arrow on About, Support, and Privacy, and the site menu,
   a ☰ button that opens a short list on every page:
   - About, Support, and Privacy, the current page in bold;
   - a Language row that unfolds in place to list the languages, the
     current one ticked;
   - the App Store badge.
   The menu and its Language row are <details> elements, so both open without
   a script, with a short animation. language.js closes the menu on a tap
   elsewhere or Escape, plays the closing and folding animations, folds the
   languages away again, and remembers a language choice. */
