   INNOVATIVE BLUE/WHITE VERSION - Construction & Luxury
   ============================================

   ⚠️  TEST VERSION: Innovative Design for Construction & Luxury Services
   - White background with architectural blueprint patterns (NO PARTICLES)
   - Blue accents with glassmorphism effects
   - Architectural grid lines and elegant flowing curves
   - Construction-themed geometric elements (blueprint style)
   - 3D card interactions with luxury feel
   - Clean, sophisticated, and disruptive aesthetic
   - Simple solid blue color for headlines (no gradients/effects)

   This is a TEST file for the innovative design.
   DO NOT use in production without thorough testing.
