Build me a custom firmware project for Samsung Galaxy devices that takes Samsung stock firmware, applies the needed patches and tweaks, and then builds a flashable zip for a target device.

I want it to feel like a polished One UI based ROM with better performance, smoother animations, live blur, extra device features, and a bunch of power user options like hiding apps, bypassing some app restrictions, and enabling useful Samsung features that are normally disabled. Include an easy update flow with an integrated OTA updater app, and make it possible to build everything from the command line in a repeatable way.

If anything depends on current Samsung tools or Android build details, look up the latest docs online and use the right approach. Keep it focused on working end to end, from pulling the firmware and building the image to producing the final package I can flash.
