derdacavga/Wireless-Keyboard ? reverse-engineered prompt

Build me a DIY wireless keyboard for a PC using an ESP32 S3 and a touch screen.

I want it to connect over Bluetooth Low Energy and show a full on screen QWERTY keyboard on an ILI9341 touch display, so I can type into my computer remotely like a normal Bluetooth keyboard. Please include a simple setup flow for touch calibration first, then the main keyboard app that uses the saved calibration values. I also want two keyboard pages so I can switch between normal letters and extra special characters. Keep it battery friendly and reliable for a portable build.

Make it easy to pair with a computer, and use clear on screen buttons so the whole display feels like the keyboard. If anything needs current library or board setup details, look them up online and use the latest stable guidance.
