+"""Golden-master snapshots for the trickiest vendor transformations.
+
+These freeze to_config() output BEFORE the collapse refactor and must stay green
+throughout it. The broader tests/custom/test_*_vendors.py suite guards the rote
+classes; this file targets the classes with custom __init__, sample_rate logic,
+cross-vendor inheritance, or aliases.
