Every defined layer, in index order — layerNames()[i] is the layer whose bit
is 1 << i.
A fresh copy, not the live array: the registry's ordering is its bit
assignment, and handing out a mutable view would let a caller renumber every
mask in the process. This is what a §79 writer emits so that a reader can
reproduce the assignment (see the module header).
