Previous version had three inelegancies visible on GitHub:
- Full-width ghost rule read as an artifact dividing the banner in half
- Top terracotta bar looked like site header chrome
- Radial gradient created compression banding at CDN quality
v5 design:
- Terracotta rounded-rect logo mark (130px) with Paper 'A' inside —
the actual brand element per the style guide, not a floating letter
- Flat Shell / Paper background — compresses losslessly, zero banding
- No top bar, no ghost rule, no gradient gimmicks
- Same crisp Cormorant Garamond SemiBold + 2x supersample + Lanczos
- Both dark and light variants updated with identical layout
