/* ==========================================================================
   Vesopa AI — the guide that hovers on the right of every page.

   Mounted on <html>, beside the loading bar, so the no-reload router's body
   swap never touches it. Two shapes: the orb and the chat. The orb is calm
   and still until tapped; beside it an introduction once a visit, and a
   caption while voice is on. On a phone the chat is a bottom sheet; from a
   tablet up it is a column down the right-hand side over the page. The
   orb's ring says what it is doing — idle, listening (grows with the voice),
   thinking, working on the page, speaking.
