+name: Dependabot auto-merge

+# Turns on GitHub's native auto-merge for Dependabot pull requests, so a PR whose
+# every required status check passes merges itself instead of waiting for a human.
+# Branch protection still fully gates the merge — nothing red lands, and required
+# checks/reviews are still enforced.
+#
+# Scope: minor and patch updates only. Major bumps are left open for a human to read
+# the changelog first. Uses only the automatic GITHUB_TOKEN — no PAT or extra secrets.
+# Requires "Allow auto-merge" in Settings > General (enabled for this repo).
+#
+# dependabot/fetch-metadata is SHA-pinned and listed in .github/allowed-actions.txt
+# plus the repository's selected-actions setting, as this repo's allowlist requires.
