/* =========================================================
   PRIME DATA GH - support chat widget
   Loaded AFTER style.css / extras.css. Only adds new classes;
   does not override any existing rule. Uses the same colour
   tokens as the rest of the site (--bg, --surface, --border,
   --text, --muted, --blue, --teal ...).

   z-index reference (see extras.css for the rest of the stack):
     bottom-nav 20, this launcher 22, consent 30, toast 40,
     this backdrop/sheet 55/65 (same tier as the payment sheet).
