 * BLOCKEXPLORER DESIGN SYSTEM - "ELECTRIC GLASS" PURPLE/BLUE EDITION
 * ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 *
 * DESIGN IDENTITY:
 * This is the BlockExplorer - A technical blockchain data visualization tool
 * Theme: Purple/Blue "Liquid Glassmorphism" for professional, technical aesthetic
 *
 * IMPORTANT - COLOR SEPARATION:
 * ┌─────────────────────────────────────────────────────────────────────────┐
 * │ BlockExplorer = Purple/Blue (#8a2be2, #4169e1, #00d4ff)                │
 * │ Fulgura DEX   = Green Brand (#C5EE49) - SEE DEX PROJECT                │
 * └─────────────────────────────────────────────────────────────────────────┘
 *
 * DESIGN PHILOSOPHY - "ELECTRIC GLASS":
 *
 * 1. DEPTH: Purple (#8a2be2) represents blockchain depth & cryptographic security
 * 2. TRUST: Royal Blue (#4169e1) represents reliability & data transparency
 * 3. CLARITY: Cyan (#00d4ff) represents data precision & analytical insights
 * 4. GLASS: Translucent layers showcase technical sophistication & complexity
 *
 * Visual Language: Premium glassmorphism with purple-blue gradients creates
 * a technical, trustworthy atmosphere distinct from trading/DEX platforms.
 *
 * Inspiration: SiteCom, Apple Design, Vercel, Stripe Dashboard
 * Updated: 2025-11-24
