/* ============================================================
   Martina web chat - standalone stylesheet.

   Self-contained copy of the ".tchat" rules from assets/css/styles.css, for
   embedding the widget on sites that do NOT load our main stylesheet - the
   HubSpot knowledge base at help.abtrace.co in particular.

   Differences from styles.css:
     - the design tokens it needs are redeclared on .tchat itself, not :root,
       so nothing leaks into the host page's own theme;
     - @font-face src paths are absolute (www.abtrace.com), since the host page
       is on another origin. CloudFront serves /assets/* with
       Access-Control-Allow-Origin: *, so the cross-origin fetch is allowed;
     - a box-sizing/line-height guard, because a host theme's base rules would
       otherwise leak into the widget.

   Keep in sync with the ".tchat" section of assets/css/styles.css.
