# Same split as `codspeed-comment.yaml`: a `pull_request` run from a fork gets
# a read-only token however it is configured, so the comparison is computed
# there and handed over as an artifact, and this workflow -- which
# `workflow_run` always runs in the base repo's context -- is the one trusted
# with a token that may write the comment.
