The install list loses the dock, the window helper, the Chrome window arbiter, the notification wrapper, the compositor and bar configs and the GTK icon and stylesheet machinery, and gains a look and feel package, a colour scheme, window rules, Kiosk restrictions and two supervised user services. Dependencies follow: Plasma and SDDM in, sway, waybar, mako and gtk-layer-shell out. Co-Authored-By: Claude Opus 5 <[email protected]>

UI_SCALE is the display's scale factor, so it scales the browser, VLC, the
|
|
bar and every dialog together rather than each of them separately. Plasma
|
|
owns display configuration, so this asks Plasma's own tool to do it — which
|
|
is the whole of what replaced the compositor-specific version.
