Bare generator extracted from andraniksargsyan/migan migan_pipeline_v2.onnx — upstream's bundled pre/post-processing (NonZero bbox crop, blur blend, ScatterND paste-back) prevents CoreML from compiling the model, so the wrapper is cut and reimplemented host-side.

Cut points: /Concat_23_output_0 → /model/synthesis/b512/Add_1_output_0. Validated against upstream's own intermediate tensors: preprocessing bit-exact, generator to float32 epsilon (2.4e-07).
