My attempt at a definition of a desktop shell would be: The collection of all the software that aids a compositor (or a window manager on X11) in providing a more complete desktop experience. Now that's kind of vague and probably also not quite correct, so a more concrete explanation would be: A program or collection of programs that gives you desktop notifications, a taskbar (with a system tray), volume controls and more stuff like that, maybe even a neat menu to configure most of this. Usually for standalone compositors/window managers you'd usually use a collection of tools like dunst, polybar, and the like, but with newer tools like quickshell, which was used here, it's reasonably easy to build a single tool which handles most of that. And that's what we're looking at here ^^
