The hull moves to the top layer, with its transparent opening and empty input
region, so windows sliding out of the opening during a workspace switch pass
behind the frame like things behind a porthole rim rather than drawing over
the bar. A layer rule keeps the bar and the rail above it on that layer.
The animation tree is redone around that: workspaces drift 18% vertically
and fade on a slow, jolt-free "drift" curve; the SUPER+S scratchpad slides in
whole from under the bar, the same gesture as the dashboard and popouts;
windows and layers keep their calm resolve and fade.
