/**
 * Tests for dom-snapshot.ts: DOM snapshot engine.
 *
 * Since the engine generates JavaScript strings for in-page evaluation,
 * these tests validate:
 * 1. The generated code is syntactically valid JS
 * 2. Options are correctly embedded
 * 3. The output structure matches expected format
 * 4. All features are present (Shadow DOM, iframe, table, diff, etc.)
