# A few notes:
#
# Variables:
# GitHub actions don't have variables or even support normal yaml anchors (they
# are specially disabled because...reasons?):
# See https://github.com/github-community/community/discussions/4501
# https://github.community/t/support-for-yaml-anchors/16128/92
# https://github.com/actions/runner/issues/1182
# Neither does it have any contexts that are available everywhere. The
# top-level `env` field is available in many places, but not all. We already
# have a "setup" job that every other job depends on, so we leverage that
# for variables that every other job can use, since that *is* available in all
# sub-fields of the job.
# See https://docs.github.com/en/actions/learn-github-actions/contexts#context-availability
# and https://github.com/community/community/discussions/27370
