At GitHub's ~840px README width, 2172×724 renders at 840×280px.
Previous element sizes (mark 130px, wordmark 80px) became 50px and 31px
at display — too small to read clearly.
Scale everything ~1.65× to fill ~80% of banner height:
mark 130 → 216px at target (≈ 83px at 840px display)
wordmark 80 → 132px at target (≈ 51px at display)
tagline 38 → 62px at target (≈ 24px at display)
A in mark 96 → 160px at target
Proportional gap increases maintain the same visual rhythm.
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
