1. The iMac G3 loads a page with a form in its browser
2. I type a message and hit send (plain HTML form POST)
3. The Pi Zero 2W I have hooked up receives the form submission and makes an HTTP request to the OpenClaw gateway’s /v1/chat/completions endpoint on the VPS
4. The VPS runs OpenClaw
5. The response comes back through the Pi to the iMac as a page reload with the full conversation
