Demonbane18/relmio ? reverse-engineered prompt

Build me a local setup wizard for Relmio that helps someone safely install and test OpenAI sign in support beside a self hosted n8n instance.

I want it to open in the browser on a private 127.0.0.1 address, check whether Docker is running, show the exact plan before doing anything, and make me confirm before it writes any local files or creates the sidecar. It should clearly separate ChatGPT sign in, OpenAI API keys, and local client access so they are not mixed together.

The wizard should support the main flows from the README, including an OpenAI compatible local endpoint, the experimental Codex options, and a private n8n sidecar that stays inside the existing Docker network. Please keep everything locked down to localhost, and make the security warnings obvious so nobody accidentally exposes it to the internet.

If you need current docs or API details while building it, look them up online first.
