Answer
By allowing behavior extension without modifying existing code.
The Open/Closed Principle states that software entities should be open for extension but closed for modification. The Decorator pattern achieves this by enabling new behaviors to be added to objects without altering their existing code. For example, adding new promotional rules to a store can be done by creating new decorators rather than changing the core product or pricing logic.
