/* 
Design Concept: "Asymmetric Glassmorphism" 
- Split-screen layouts with 60/40 proportions create visual tension
- Glassmorphism elements provide depth and premium feel
- Animated gradients and floating elements add modern dynamism
- Typography pairing (Playfair + Inter) balances elegance with readability
- Organic shapes and subtle animations create friendly, approachable interface
