SuperTonic 3 (MLX conversion) — attribution notice

Original model: SuperTonic 3 by Supertone Inc.

These weights were format-converted from the original ONNX exports (fp32,
opset 19, `onnx/` directory of Supertone/supertonic-3) to MLX safetensors.
They are MODIFIED FILES in the sense of the license: numerical values are
unchanged, but the container format, tensor key names, and Conv weight axis
order ([O,I,K] -> [O,K,I]) differ from the originals. The classifier-free-
guidance scale (4.0) and the Euler integration step that are baked into the
original vector_estimator.onnx graph are NOT baked into these weights; they
are applied by the consuming runtime (mlx-audio-swift `SupertonicModel`).
