   Design notes (inspired by spline.design + design.dev):
   • Liquid-glass surfaces via backdrop-filter on every elevated card
   • Ambient glow orbs + conic-gradient rings for depth (Spline's 3D feel)
   • SVG feTurbulence grain layer to kill gradient banding
   • OKLCH-aware token ramps so hues stay perceptually even across themes
