+The **decoupled Nervous System** for the monorepo. 
+
+Provides a highly performant, strictly typed Event Bus (Pub/Sub) powered by `mitt`. It allows independent modules to communicate seamlessly without tightly coupling their codebases or triggering expensive global React tree re-renders.
+
+**Key Capabilities**:
+
+| Feature | Description |
+|---|---|
+| 🧩 Zero Coupling | Publishers and subscribers interact via blind events, eliminating direct module imports and circular dependencies. |
+| ⚡ Extreme Performance | Enables targeted DOM updates for high-frequency data streams (e.g., WebSockets) without re-rendering parent components. |
+| 🧹 Memory Safety | Native `useAppEvent` hook automatically unsubscribes on component unmount, preventing SPA memory leaks. |
+| 🛡️ Strict Contracts | Centralized `events.registry.ts` enforces payload shapes via TypeScript, ensuring cross-module data safety. |
+
+**Documentation**: [README.md](packages/core-events/README.md)
