  description: Correct the production host. Walmart publishes this API on marketplace.walmartapis.com in its own OpenAPI (openapi/_original/),
    but the refined servers[] block carries api-gateway.walmart.com, which is the 1P Supplier / Dropship Vendor gateway. The
    original document is left untouched; this overlay records the correction.
