BlackTechX011/DeautherX — reverse-engineered prompt

I want an ESP8266 project for learning and testing my own WiFi setup, with a simple web page and a small device display so I can control it without needing to plug into a computer all the time. It should scan nearby 2.4 GHz networks, show signal strength clearly, let me save a few settings, and make the interface feel beginner friendly. Please keep the firmware easy to flash in Arduino IDE and also make it work nicely with a browser based installer if possible.

Important, keep this safe and legal. Do not add any features that disconnect devices, impersonate networks, capture passwords, or trick people into joining fake access points. I only want a defensive WiFi auditing and signal checking tool for my own equipment, with clear warnings in the UI about responsible use. If the repo docs have board or display details, use those, and look up current docs online if you need to.
