Create a parent component with three child components: Inventory Summary (A), Stock Update (B), and Notification Panel (C). The challenge focuses on implementing a robust communication mechanism where Stock Update (B) and Notification Panel (C) can dynamically exchange information with minimal performance overhead. Your solution should address the following key requirements: 1. Implement a lightweight data sharing mechanism between components B and C 2. Ensure real-time updates are propagated efficiently without causing unnecessary re-renders 3. Develop a parent component that manages and coordinates the interactions between child components 4. Design the components to handle potential high-frequency inventory updates without compromising system performance 5. Include appropriate error handling and state management strategies to maintain data consistency The goal is to create a scalable and performant LWC architecture that can handle complex inter-component communication while maintaining optimal rendering and update cycles.
