Rewrite my ./generated/modules/traveldroid/desktop/stylix.nix  to integrate nicely with my existing flake.nix en host.nix
Avoid infinite recursion
Just look at how to rewrite this, ignore previous interactions around this nix.
Solve the error. That is really important.
Look at hyprland.nix to see how to avoid the home error
