/* ══════════════════════════════════════════════════════════════
   EngineOS Live Chat Widget — Dribbble-style Floating Chat Widget
   Rebuilt to match "Floating Chat Widget" by Aryabh (Dribbble shot
   21652548). One cohesive floating panel: gradient header, bot
   greeting bubble, primary CTA + quick-option tiles, channel pills,
   search composer, and a conversation window with pill composer.

   The root element is created with id="eos-chat-widget" and the
   dedicated class alias .chat-support-widget is applied on the same
   element. Every selector is prefixed with the unique #eos-chat-widget
   id so that reset blocks and the host page's global CSS can never
   override the widget's own spacing/typography (specificity > any
   page-wide class/type selector). Nothing leaks in or out.
