Build me a NixOS flake based system setup for my own machines.

I want a repo that can install a minimal base system first, then let me switch into a fuller desktop setup later. It should support at least three choices, one for a minimal install, one for a WSL style setup, and one for a regular NixOS desktop machine. Please make it easy to clone, enter a dev shell, run the disk setup, and install the system with simple commands.

Keep the configuration organized in separate folders for hosts, system settings, home settings, packages, and any secrets handling if needed. I’d also like a small helper workflow so rebuilding and switching is straightforward after the install. If you need to check current best practices for NixOS, flake, or disk setup, look up the latest docs online.
