# This is the CI workflow (not the artifact build/release workflow). The workflows
# are split because GHA doesn't support a dynamic/conditional matrix. This workflow
# has slow jobs and jobs that require private GHA runners (eg, M1 Mac) commented out.defaults:
# Ensure changes are synced with manual_artifact_build.yaml.
