/* Reseller Chat — customer-facing widget. Rendered on reseller storefronts
   (NOT on reuzeit.com — the bot stays there). Conditional include lives in
   views/layouts/main.php gated on Yii::$app->params['reseller']['enabled'].

   Visual language mirrors the Reuzeit "Support live Chat" bot widget
   (defined in global.css), but every colored surface uses CSS custom
   properties so each reseller's --primary/--primary-gradient theme paints
   the header + bubble in their own brand color.

   Layout:
     [floating bubble (closed) / X close (open) at bottom-right]
     [panel]
       [header: gradient + title + sparkle]
       [pill row: "support" tag]
       [body: empty-state illustration OR list of message rows]
         each row = [avatar circle (initial)] [name / text / timestamp]
       [input row: text input + paper-plane send] */

/* Hard yield to the AI-Chat shop/support widget — the moment ANY .chat-box
   exists on the page (Reuzeit bot or AI-Chat product-search widget on
   shop/category pages), hide our standalone widget so the page never shows
   two stacked chat icons. This is the CSS-only safety net; the JS-side
   MutationObserver in reseller-chat-widget.js also tears the widget down
   when .chat-box is injected after our boot. Together they cover initial
   render, AJAX/pjax page swaps, and stale-state cases.
