foxlet/macOS-Simple-KVM ? reverse-engineered prompt

Build me a simple set of scripts and docs that lets me run macOS in a virtual machine on Linux with QEMU and KVM.

I want it to be easy for someone who is not super technical. It should help download the macOS installer, create an empty virtual disk, and start the VM so I can install macOS. Make the default setup use Catalina, but let me choose High Sierra or Mojave too. I also want a headless option for servers or cloud machines, with VNC access, plus a way to import the setup into Virt Manager if that’s easier.

Please include clear getting started steps, a few helpful notes about what Linux packages are needed, and simple guidance for adding storage, memory, networking, and better screen resolution later. If you need to, look up current docs online so the instructions still work.
