+# on the first commit of a branch, not only once a PR targets main. No
+# separate pull_request trigger: for a PR from a branch on this same repo,
+# push already fires on that branch, and GitHub attaches the run to the PR
+# by commit SHA regardless of which event triggered it — adding
+# pull_request too would just run every job twice per push. (Re-add it,
+# scoped to forks, only if this repo starts accepting fork PRs — push
+# events from a fork never reach here.)
