OpenAPI Overlays for Translating and Localizing One Canonical Spec

Translation is where a lot of teams quietly fork their API contract, and they don’t even notice they’re doing it. Someone in the German office needs the docs in German, so they copy the OpenAPI file, run the summaries and descriptions through a translator, hand-fix a few things, and now there are two specs. Then the English one gets a new endpoint, or a rate-limit header changes, or an error message gets reworded, and the German copy drifts.
