| `OpaqueResponse` objects are immutable but constructable. The `fetch()` API |
| returns this type for cross-origin responses. |
| Their role is to encapsulate the security properties of the web platform. As |
| such, their `body` attribute will always be `undefined` and the list of |
| readable `headers` is heavily filtered. |
| `OpaqueResponse` objects may be forwarded on to rendering documents in exactly |
| the same way as mutable `Response` objects. |
