+# Vendored third-party browser bundles (US09-01). Minified upstream files carry
+# trailing whitespace and very long lines; they are not ours to reformat, and the
+# submit gate's `git diff --check` would refuse them forever. Their integrity is
+# controlled where it belongs instead: a pinned version and a recorded sha256 in
+# frontend/js/vendor/VERSIONS.json, asserted by tests/integration/test_documentation.py.
+#
+# Only the whitespace check is turned off. They stay text, so a credential scan or a
+# search still reads them.
