/**
 * This module implements an Interface Adapter Pattern to integrate Preact's
 * rendering system with Lynx's custom Snapshot-based virtual DOM.
 *
 * It works by:
 * 1. Defining a minimal {@link Document}-like interface that Preact expects
 * 2. Implementing this interface to return our {@link Snapshot} instances
 * 3. Maintaining the same method signatures as the standard DOM API
 *
 * This allows Preact to build its virtual tree using our Snapshot system
 * without knowing it's not working with a real DOM.
