// Scoped to the TextareaComposer's own elements (not the composer-controls
// wrapper) so the textarea fills its container in any composer layout — e.g.
// a custom composer that renders <TextareaComposer> without the default
// MessageComposerUI. Without this the bare <textarea> falls back to its
// intrinsic `cols` width (~160px).
