# This job runs if all the `nox-cross-arch` matrix jobs ran and succeeded.
# As the `nox-all` job, its main purpose is to provide a single point of
# reference in branch protection rules, similar to how `nox-all` operates.
# However, there's a crucial difference: the `nox-cross-arch` job is omitted
# in PRs. Without the `nox-cross-arch-all` job, the inner matrix wouldn't be
# expanded in such scenarios. This would lead to the CI indefinitely waiting
# for these jobs to complete due to the branch protection rules, essentially
# causing it to hang. This behavior is tied to a recognized GitHub matrices
# issue when certain jobs are skipped. For a deeper understanding, refer to:
