(code int, name string, data any)

	// as Renderer.Render can fail, and in that case we need to delay sending status code to the client until
	// (global) error handler decides the correct status code for the error to be sent to the client, so we need to write
	//  the rendered template to the buffer first.
	//
	// html.Template.ExecuteTemplate() documentations writes:
	// > If an error occurs executing the template or writing its output,
	// > execution stops, but partial results may already have been written to
	// > the output writer.
