+name: Dependabot auto-merge
+
+# Enables GitHub's native auto-merge on Dependabot PRs for patch/minor bumps.
+# The PR is only merged once every *required* status check on `main` passes
+# (lint, build, e2e, audit) — auto-merge does the waiting; this workflow just
+# turns it on. Major version bumps are left open for manual review.
