+name: Auto Format
+
+# Stage 1 of 2 (producer). Runs with the default read-only token and never
+# pushes or comments, so it is safe to format PR-authored code — including
+# from forks. The companion "Auto Format — Apply" workflow (triggered by
+# workflow_run) commits the result back with elevated permissions, isolated
+# from PR-authored code.
