/**
 * @fileoverview Integration tests for preset accessibility
 *
 * Tests that preset content is accessible without filesystem dependencies,
 * validating that the inlined preset approach works correctly for both
 * development and bundled distribution contexts.
 *
 * These tests verify:
 * - All 5 presets can be loaded without filesystem access
 * - Preset content contains required markers for loop completion detection
 * - Preset content structure is valid and usable by the loop system
