Solution
An npm Shadow-DOM widget plus a Cloudflare Worker agent: SSE streaming, Durable Object sessions, rate/spam guards, lead capture, mic input, and Groq neural TTS.

Where AI fits
LangGraph orchestrates the conversation; voice in the browser and neural TTS from Groq make it feel like a real greeter — not a form.

Outcome
Published as ai-voice-bot-widget on npm; agent backend live at voicebot.devmohan.in.
