Spark-only embeddable chat widget with **guided navigation**, session persistence, and site-wide install support. Use this package for assistants created via Spark onboarding — not the standard `@helllo-ai/agent-chat-widget`.

<script>
  window.AgentChatWidget.init({
    agentId: 'your-agent-id',
    embedKey: 'your-embed-key',
    title: 'Chat with us',
    primaryColor: '#2664eb',
    enableGuidedNavigation: true,
    sessionPersistTtlMs: 1800000,
    position: 'bottom-right',
    viewType: 'rail'
  });
</script>
```
