  # hosts/default.nix to generate the full set of NixOS configurations.

  # Structure:
  #   <host-type> = {
  #     count = <number>;       # Number of hosts to generate (e.g., nix-laptop1, nix-laptop2)
  #     devices = {             # Per-device overrides
  #       "<index>" = {

  #         flakeUrl = "...";      # Optional external system flake for full override
  #         ...                    # Other hardware/filesystem overrides
  #       };
