  title: Amazon S3 Configure and Verify Bucket CORS
  summary: Put a bucket CORS configuration then read it back to confirm.
  description: >-
    A browser-access flow for Amazon S3. The workflow writes a Cross-Origin
    Resource Sharing (CORS) configuration to the bucket so that web clients on
    other origins can call the bucket, and then reads the configuration back to
    confirm the rules are in effect. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
