   Folio — Arthur, the chatbot (js/chatbot.js): a button bottom right that
   opens a small chat window.

   Its own file, because pages use different stylesheets (the editor and the
   sign-in pages don't load components.css). The --color-* variables come
   from pages.css; elsewhere the fallbacks from colors.css are used.
