Independent embed widget

A clean-room support messenger foundation.

This page simulates a host application. The floating messenger is injected by one script, isolated in shadow DOM, and can be branded or wired to your own assistant endpoint.

<script>
  window.MessengerWidgetSettings = {
    brandName: "Your product",
    agentName: "Nova",
    endpoint: "/api/chat"
  };
</script>
<script src="./widget.js" defer></script>
