      # pins target-cpu=znver5 for local AVX-512 codegen, which SIGILLs
      # on the Actions runner CPU. Override to a portable baseline that
      # still keeps AVX2 so the lints + tests are meaningful.

        # Pinned snapshot. The unpinned `nightly` channel drifts rustfmt
        # and clippy rules between runs, which has historically broken
        # CI on unchanged code. Bump deliberately, not by accident.
