Github — Design Score: 92/100 (grade A)
GitHub's design is polished across the board (A-grade consistency); only gap is flat surfaces lack depth cues—no real cost to core tasks.

The four measured dimensions
- Typography & Hierarchy: 96/100
- Color & Contrast: 90/100
- Spacing & Layout: 91/100
- Motion & Polish: 90/100
What we measured
- Typography & Hierarchy — type ladder rhythm: 1.60× · 1.82× · 1.22× · 1.12× (33.9/35)
- Typography & Hierarchy — weight contrast: [400, 425, 460, 480, 500, 600] (spread 200) (17.1/20)
- Typography & Hierarchy — body line-height: 1.50 (15.0/15)
- Typography & Hierarchy — heading line-height: 1.08 (10.0/10)
- Typography & Hierarchy — size discipline: 5 (20.0/20)
- Color & Contrast — body text contrast (WCAG): 17.39:1 (30.0/30)
- Color & Contrast — primary button contrast: 4.66:1 (10.0/10)
- Color & Contrast — accent discipline: 3 (20.0/20)
- Color & Contrast — surface coverage: 65% dominant (20.0/20)
- Color & Contrast — scheme consistency: light (10.0/20)
- Spacing & Layout — spacing grid: 4px grid · 89% confidence (31.2/35)
- Spacing & Layout — grid adherence: 10/12 on 4px (20.8/25)
- Spacing & Layout — breathing room: 0.31 density · regular (24.4/25)
- Spacing & Layout — structure & responsive: 2 breakpoints (15.0/15)
- Motion & Polish — motion tokens: 200ms dominant (25.0/25)
- Motion & Polish — choreography: 15 reveal candidates (20.0/20)
Every line above is read from the live DOM — the exact contrast ratio, the detected spacing grid, the forced hover states — not an AI's guess from a screenshot.
Top fixes
- Add subtle shadow elevation tokens to interactive surfaces
- Expand weight contrast in heading hierarchy
- Increase dark-mode color scheme depth measurement
