/**
 * MEDIATOR PATTERN
 *
 * <p>Purpose: Centralizes communication between components, reducing direct connections and dependencies.
 *
 * <p>When to use:
 * <ul>
 *   <li>When a set of objects communicate in well-defined but complex ways</li>
 *   <li>When reusing an object is challenging because it communicates with many other objects</li>
 * </ul>
 *
 * <p>Common Pitfalls:
 * <ul>
 *   <li>Creating a mediator that becomes a "god object"</li>
 *   <li>Not properly defining the communication protocol</li>
 * </ul>
