/* ==========================================================================
   Floating chat widget (Artemis)

   A launcher pinned bottom-left that expands into the direct-chat channels
   (WhatsApp, Messenger). Bottom-LEFT because the Facebook customer-chat plugin
   and Zoho SalesIQ both take the bottom-right corner on dev and production.

   z-index sits below Bootstrap's modal layer (1050) so the delete/confirm/message
   modals in the shop layout still cover it.

   Paired with:
     resources/views/project/layouts/shop/includes/sections/chat-widget.blade.php
