   GoTravelista · Live Chat widget
   Replaces the header Call / WhatsApp CTAs (desktop + mobile).
   Palette + type tokens come from theme-2026.css — this file defines no
   colours of its own beyond the chat-specific tints, so a brand change in
   the design system carries through here without an edit.

   z-index ladder on this site (do not reshuffle casually):
