Where a module's layers go in the map's layer stack, as one BeforeLayerConfig for the
whole module or one per part of it.
Type Parameters
PARTextendsstring
The names of the module's parts that move independently.
Remarks
In the record form, a part takes its own entry, otherwise all. A part that neither names stays
where the module puts it by default. A part's own layers keep their order wherever it goes.
