   DeepCast AI — Human-first design

   Design principles:
   - No purple/blue gradients (AI cliché)
   - Serif headings for warmth and editorial feel
   - Off-white/warm tones instead of pure white on black
   - Asymmetric rhythm, not pixel-perfect grids
   - Minimal decoration, let content breathe
