IAB stars twinkle in docs tonight.
One call, one name, and the categories sing,
Topics and keywords on the springtime wing.

- Around line 264-266: Add the missing ErrorResponse payload schema to the 420
response for the chat/completions path so it matches the /responses error
contract. Update the relevant OpenAPI response entry in
zlm-v1-iab-domain-classifier.openapi.json, keeping the same error structure used
elsewhere for 420 responses and aligning the chat/completions documentation with
the existing response schema.
