Strategies encapsulate interchangeable algorithms behind a shared interface, letting clients swap behaviors at runtime.
Use polymorphism to replace branching logic; e.g., each NotificationChannel implements its own send() method.
The visitor pattern leverages double dispatch to separate operations from object structures.
