Purpose	Decoupled communication between UI Kit components — subscribe to events to react to changes without direct component references

Events provide decoupled communication between UI Kit components. Components emit events in response to user interactions or state changes, allowing other parts of the application to react without direct component references.

Both Components and Composite Components have the ability to emit events. By emitting events, these components allow other parts of the application to react to changes or interactions, enabling dynamic and interactive behavior within the application.
