   NEXIFY STUDIO: the language switch (js/i18n.js), Deutsch / English.
   The same liquid glass as the sun/moon switch beside it: a glass pill with a
   lens that slides under the chosen language (stretching a little as it
   travels) and two round flags. It sits in the hero header, in the floating
   bar, and on phones in the menu with the full language names.
