loading property

bool get loading

When true, the renderer paints a shimmer placeholder over the image area instead of the actual url. Use this when the backend has triggered an async generation (e.g. a nail design render) and wants the chat surface to feel alive while the task is still pending. The accompanying card typically carries a callback action whose payload.task_id the host polls; when the task resolves, the host updates the message in place with loading: false and the real URL.
