        Spec published at https://docs.worldlabs.ai/api/reference/openapi.yaml.
        Strong schema coverage (46 component schemas, examples on request
        bodies); operationIds are FastAPI-generated (verbose); no 401/429
        responses declared even though the API enforces API-key auth and rate
        limits; errors use a detail-field envelope, not RFC 9457.

        Authenticate with the WLT-Api-Key header. worlds:generate returns an
        operation_id; poll GET /marble/v1/operations/{operation_id} until done
        is true (generations take about 5 minutes). Upload local media via
        media-assets:prepare_upload before generation. On 429 honor
        Retry-After with exponential backoff and jitter.
