/* Shared phone-call demo (public/js/call-demo.js). Scoped under .kcd so it
   drops into either site. Speaker colours never reuse verdict colours:
   AI = sky blue, caller = warm grey; red / amber / green belong to the risk
   meter and the verdict. The phone screen is dark like a real call screen;
   the page around it stays light. */
