/**
 * The Error arm of the four-state contract: renders the message and, when a retry
 * handler is supplied, a `<screenTag>_retry` control with a 48 dp touch target. The
 * error state is a rendered, testable affordance — not just a ViewModel arm.
 *
 * @param message User-facing copy. Presentation maps a `DomainError` kind to it; never
 *   pass a raw exception string.
 * @param screenTag Feature slug; derives the `<screenTag>_error` and `<screenTag>_retry` tags.
 * @param onRetry Non-null renders the retry control; null renders the message alone.
