+  # The next version comes from the conventional PR title: `type!:` is a
+  # breaking change (major), `feat:` is minor, anything else is patch.
+  # A `semver:*` label overrides the title in either direction: these rules
+  # come first and are exclusive, so the title rules below are skipped for a
+  # labeled PR. The labels are deliberately not named `major`/`minor`/`patch`,
+  # because Dependabot adds labels with those exact names to its PRs whenever
+  # they exist in the repository.
