## TL;DR

Defines an interface for creating objects, letting subclasses decide which class to instantiate. Defers instantiation to subclasses.

## Core Explanation

Creator (abstract with factory method) + ConcreteCreator + Product interface. In modern code, factory functions (plain functions returning objects) often suffice without class hierarchies. Abstract Factory creates families of related objects (e.g., GUI widgets per platform).
