Makes it easier to use stylix without depending on other parts of the
desktop. Mainly useful for using stylix with the phone module without
including desktop-related stuff.
This continues the process of simplifying the available modules for
end-users. The final result would be having a clear set of modules like
"desktop" and "shell" that can be enabled if users want a complete
Hyprland environment or a complete shell environment.
Enabling the stylix module "only" would be a low-tech solution and at
that point it'd likely be better for end-users to take complete control
of their stylix config with their own module.
