LelandSindt/locator ? reverse-engineered prompt

Build me a small Python tool called Locator that I can run locally or in Docker.

I want it to use a cookies file exported from Firefox for google.com, plus a settings.env file for configuration. Make it easy to set up, with simple scripts to run it locally and in Docker, and clear instructions for how to copy the example env file and fill in my own settings.

If the project needs any extra setup steps or current docs to make the Google cookie export work smoothly, look those up online and wire it in the simplest way possible. Keep the code and setup straightforward, and make sure it fails with helpful messages if the cookies or settings are missing.
