/* 
Design Philosophy: Modern Glassmorphism with Gradient Mesh
This design uses floating glass elements, vibrant gradient overlays, and sophisticated 
backdrop blur effects to create a cutting-edge aesthetic perfect for a design studio.
Key features: translucent cards, animated gradients, depth through layering, and 
subtle hover interactions that showcase modern web design capabilities.
