/* Customer support chat -- the messaging surface shared by the signed-in
   Support screen (public/account.html) and the guest widget
   (public/guestChat.js). Same-origin stylesheet: the pages' CSP is
   hash-based and forbids style="" attributes, so every rule lives here.

   Tokens are scoped to .sc so an installation can retint the chat
   without touching the rest of its pages. The brand NAME comes from the
   server (lib/siteBranding.js), never from this file. */
