style: match Stitch glassmorphism — backdrop-blur, flag glow auras, deeper shadows

Hero card now uses glassmorphism (rgba + backdrop-blur) from Stitch design.
Each flag has individual blur-glow aura behind it.
Rounded corners increased to 2rem. Shadow depth increased.
Stats tiles and nudges also refined with rounder corners.
