/* Persistent toggle left behind when the banner auto-hides after 5s

   deliberately small — it sits on the login screen indefinitely while the
   app isn't installed, so it has to stay out of the way in a way the full
   banner doesn't. Bottom-right rather than the banner's centred position:
   the login card's own content runs down the middle, and a corner pill
   doesn't need the scroll-reservation dance the full-width banner does. */
