You're refactoring a higher-order component that injects props into wrapped components. You notice that the component tree is getting deeper and more complex. Which pattern can help flatten the component tree while still sharing the logic?

The Proxy Pattern can help flatten the component tree while still sharing the logic. It allows you to control access to an object by creating a surrogate or placeholder for it. In the context of React or similar frameworks, a proxy component can be used to encapsulate complex logic, making the component tree shallower and more maintainable. The other patterns listed do not directly address this issue.
