Despite having read about it multiple times I still don't feel like I know what it is. My best guess is that it's an operating system, minus the kernel? But also it can be used as a GTK/Qt type interface layer? Or it can be used to replace X/Wayland? So like, a super modular operating system? And now I guess it's also a web browser, or a generalization of web-browser-like things that may or may not actually be compatible with the traditional web?
