* ),
* "<html>Hello world!</html>\n"

*
* This class implements the
* [PSR-7 `ResponseInterface`](https://www.php-fig.org/psr/psr-7/#33-psrhttpmessageresponseinterface)
* which in turn extends the
* [PSR-7 `MessageInterface`](https://www.php-fig.org/psr/psr-7/#31-psrhttpmessagemessageinterface).
*
* On top of this, this class implements the
* [PSR-7 Message Util `StatusCodeInterface`](https://github.com/php-fig/http-message-util/blob/master/src/StatusCodeInterface.php)
* which means that most common HTTP status codes are available as class
* constants with the `STATUS_*` prefix. For instance, the `200 OK` and
* `404 Not Found` status codes can used as `Response::STATUS_OK` and
* `Response::STATUS_NOT_FOUND` respectively.
*
* > Internally, this implementation builds on top of an existing incoming
* response message and only adds required streaming support. This base class is
* considered an implementation detail that may change in the future.
