krishnakanthb13/antigravity_phone_chat — reverse-engineered prompt

Build me a simple phone friendly web app that lets me watch and control my Antigravity chat from my phone while it is running on my computer. I want to start Antigravity in debug mode, run a local server, then scan a QR code or open a link on my phone and see the live chat with very fast updates.

It should work easily on the same Wi Fi without making me log in every time, but if I use it from outside my house it should require a passcode and support a public tunnel option like ngrok, Cloudflare Tunnel, or Pinggy. Please include a clean mobile interface for reading the chat, switching chat history, and sending messages back to the desktop session.

Make the setup beginner friendly with launch scripts for Windows and Mac or Linux, automatic env setup, HTTPS support, and clear terminal instructions. Keep security in mind and look up current docs online if you need to.
