# One run per pull request: a new push cancels the superseded run. The PR number is used rather
# than the head branch, which two forks can share. Pushes to main and merge groups fall back to
# the run id and never cancel each other. The group names the workflow literally
# because `github.workflow` is the caller's name inside a reusable workflow, and release.yml calls
# several of these at once.
