auto-account-creators/auto-create-facebook-accounts ? reverse-engineered prompt

Build me a Python tool that can automate creating and managing test accounts in a browser for a demo website, with smart session handling so it can resume cleanly if something gets interrupted.

I want it to open a browser, fill out signup forms, handle simple verification steps when needed, and keep track of created accounts in a local database or file so I can review what happened later. It should also support basic browser identity settings for testing different device style profiles, and make the run feel stable and human like for QA and load testing purposes. If you need to look up current docs online for the browser automation parts, go ahead. Please keep the code organized, include a clear entry point, and add a small way to run the main workflow from the command line.
