ParameterGenerator	Generate a complete named parameter tree for one target specification.
LayerGenerator	Own one trainable latent and a mapper for one flat parameter group.
LayerwiseGenerator	Assign one latent mapper to each target module that owns parameters.
LazyLayerwiseGenerator	Layerwise generator that frees each group's flat buffer as it goes.
SingleVectorGenerator	Generate every target parameter from one latent vector.
GroupedGenerator	Generate target parameters from explicit, independently mapped groups.
