+ * @brief JSON Schemas constraining structured output from OpenAIGenerator
+ * Chat Completions requests, via response_format.json_schema (Structured
+ * Outputs, strict mode). This is OpenAI's equivalent of the GBNF grammars
+ * in json_grammars.h -- the API guarantees the response message content is
+ * a single JSON string that validates against the schema, so there's no
+ * grammar-level "thought-block" prefix to account for.
+ *
+ * OpenAI's strict mode requires "additionalProperties": false on every
+ * object in the schema, which these already have.
