+      # Uses Homebrew's own `brew bump-formula-pr` (preinstalled on the runner) rather than a
+      # third-party action. mislav/bump-homebrew-formula-action breaks when GitHub's tarball
+      # endpoint returns HTTP 303 instead of 302 (see mislav/bump-homebrew-formula-action#342);
+      # the official CLI handles the redirect correctly and removes a pinned-action dependency.
