/* =========================================================================
   CHATKÎA — Embeddable Chat Widget Styles
   All colors/sizes are CSS custom properties on .chatkia-root, so a site
   integrating this widget can re-theme it entirely by overriding the
   variables below (either in their own stylesheet or inline).
   Every selector is prefixed "chatkia-" and scoped under .chatkia-root so
   dropping this onto any host page will not leak or collide with their CSS.
