+# Version updates are grouped per ecosystem/directory so each one produces a single
+# PR (and a single CI run) instead of one PR per dependency. `dev` requires branches
+# to be up to date before merging, so N separate PRs means N serial rebase + full-CI
+# cycles. Security updates are not affected: they are opened separately and immediately.
