rofi, clipmenu, feh, i3status-rust and the laptop's model module wrote files into i3's config.d,
naming no dependency on the window manager. They now contribute their lines; i3 places them under a
line naming each module, and config.d is the operator's alone. The catalogue-wide test composes the
contributions as the controller does and checks the whole with i3 -C.
Places the seat's dmenu-compatible command, the launcher and power menu, its
themes in the decided faces, and its key bindings as an i3 drop-in; Go tools
menu, applications, themes and run.
