Collapse Cascade

Definition

A cascade kind in which both axes at the trigger lose function together: the capacity disengages and the domain thins to nothing at once, leaving the center flat in both directions. One of four diagonal kinds (both axes off-center; cap−/dom−). Twenty cascades carry it.
