      # PyPI rejects binary wheels tagged `linux_x86_64`/`linux_aarch64`
      # (it requires a PEP 600 `manylinux` tag). auditwheel relinks the
      # extension against system libs, bundles anything it can't, and
      # retags it as `manylinux_*`.
      # - --plat auto picks the tightest compatible tag from the wheel's
      #   actual symbols (e.g. manylinux_2_24) — hardcoding a glibc-based
      #   tag can fail the build. repair also fails on unsupported
      #   symbols, which gates the build.
      # - The input glob must stay arch-scoped: a repaired
      #   `manylinux_2_X_<arch>.whl` still matches a bare `*linux_*.whl`
      #   but never `*linux_<arch>.whl`, so re-running can't pick it up.
      # - repair leaves the original wheel in dist/, so the `linux_*`
      #   wheel is removed before upload (would be a second 400 on PyPI).
