/**
 * WeaveFallbackRecommendations - Weave Format Fallback Component
 *
 * Displays recommendations as a fallback UI when no AdMesh links are detected
 * in the LLM response. Works independently without requiring WeaveAdFormatContext.
 *
 * This component will:
 * - Accept messageId, query, and fallback state as props
 * - Only render when fallback prop is true
 * - If previousRecommendations are provided and not empty: renders them directly (no API call)
 * - If previousRecommendations are empty/null: calls SDK's showRecommendations() to fetch recommendations
 * - Display recommendations in the specified format (tail or product)
 *
 * IMPORTANT: Pass previousRecommendations from WeaveAdFormatContainer to avoid duplicate API calls.
 *
 * @example
 * ```tsx
 * const [fallback, setFallback] = useState(false);
 *
 * <AdMeshProvider apiKey={apiKey} sessionId={sessionId}>
 *   <WeaveAdFormatContainer
 *     messageId={message.id}
 *     query={userQuery}
 *     onFallbackChange={setFallback}
 *   >
 *     {llmResponseContent}
 *   </WeaveAdFormatContainer>
 *   <WeaveFallbackRecommendations
 *     messageId={message.id}
 *     query={userQuery}
 *     format="tail"
 *     fallback={fallback}
 *     previousRecommendations={recommendations} // Pass from WeaveAdFormatContainer
 *   />
 * </AdMeshProvider>
 * ```
