/**
 * HAIVEN DESIGN SYSTEM v2.0
 * Unified design tokens and components - SINGLE SOURCE OF TRUTH
 *
 * USAGE RULES:
 * 1. ALL components must use these tokens (no hardcoded values)
 * 2. Use semantic aliases (--color-primary) in component code
 * 3. Raw tokens (--haiven-cyan) only for token definitions
 * 4. Extension and frontend share this exact system
 * 5. Never duplicate these definitions elsewhere
