Nodes now have a background using the libadwaita .card style class. Ports now have a circular handle, which is positioned on the edge of the node so that half of the circle sticks out. Ports are also no longer themed like a button and don't receive a color based on the guessed media type, in a future commit, the handle will be colored instead.
