# The jobs are split into a PR set and a full set like in ubuntu.yml (see "How
# CI runs" in docs/mkdocs/docs/community/quality_assurance.md): the PR set runs
# on every push; the full set after the PR set passed, on pushes and on pull
# requests with the "🚀 ready to merge" label. tools/ci_jobs checks that every
# job belongs to exactly one set.
