"""Behavior-level conformance tests for the ``normalization`` family.
These tests anchor the manifest-aligned ctor surface (``normalized_shape``,
``num_groups``, ``training``-in-ctor) and verify forward calls produce
real tensors. No ``inspect.signature`` parsing or
``scripts.validate_manifest`` re-imports — those metadata-pinning tests
were retired together with the same-PR-rename legacy aliases.
