/* ══════════════════════════════════════════════════════════════════════════
   Customer support chat - the widget on the website, the shop and the
   customer area (development/support-widget.js, _Shared/support-widget.php).
   SUPPORT-DESIGN.md.

   Self-contained on purpose: it sits on pages styled by many different
   templates, so everything is under #erp-support, prefixed sw-, drawn from
   its own tokens, and resets what host stylesheets are known to change
   (headings' case and size, paragraph fonts, button looks). Dark mode
   follows the visitor's system setting and the page's own theme attribute.
   Targets are 44px; motion stops under prefers-reduced-motion.
