Expand description

Middleware that styles error responses for ANY registered status code (e.g. 429, 403, 410) the way render_500_middleware does for 500. After the handler runs, if the response status has a registered template and the body isn’t already HTML, the body text is captured as the message and the template is rendered in its place — preserving the original status code.

Registered via App::builder().error_template(status, "name.html"). 404 and 500 keep their dedicated paths (not_found_template / server_error_template); this covers everything else a handler returns as Err((status, message)).
