Answer
It ensures compatibility between the base object and its decorators.
By maintaining the same interface, decorators can be used interchangeably with the original object. This allows clients to treat decorated and undecorated objects uniformly. In an e-commerce system, both a base product and a discount-decorated product can be processed the same way in the checkout logic, since they implement the same pricing interface.
