/**
 * Core Pattern Library with Pre-computed Embeddings
 * 
 * This file is auto-generated by scripts/buildPatterns.ts
 * DO NOT EDIT MANUALLY - edit src/patterns/comprehensive-library.json instead
 * 
 * Storage strategy:
 * - Patterns are bundled directly into Brainy for zero-latency access
 * - Embeddings are pre-computed and stored as binary Float32Array
 * - Total size: ~140KB (negligible for a neural library)
 * - No external files needed, works in all environments
