    # One Linux runner produces all three archives. build.py normalises
    # everything that would otherwise vary by build host — file modes, tar
    # ownership, and launcher line endings — so a Windows zip built here is
    # equivalent to one built on Windows. That removes the three-runner matrix,
    # the artifact hand-off between jobs, and the race of three jobs trying to
    # create the same release.
    #
    # Multi-OS runners would still earn their keep for *testing*, which is a
    # different question from building.
