+          # registry only carries cp312+ spglib wheels (build-spglib.yml's

+          # numpy-distutils-era setup.py hard-crashes under modern numpy
+          # (gotcha 291's addendum below). Leaving spglib unpinned lets pip
+          # take our registry's wheel where one exists (cp312+, same version
+          # as PyPI's so the wheel still wins the tie) and fall back to
