Signal — Design Score: 78/100 (grade B)
Typography and motion are locked in; body text is unreadable (1.22:1 contrast) and spacing feels cramped—fix these or lose users.

- Motion & Polish: 90/100
What we measured
- Typography & Hierarchy — type ladder rhythm: 1.50× · 1.43× · 1.40× · 1.25× (35.0/35)
- Typography & Hierarchy — weight contrast: [400, 600, 800] (spread 400) (20.0/20)
- Typography & Hierarchy — body line-height: 1.40 (15.0/15)
- Typography & Hierarchy — heading line-height: 1.07 (10.0/10)
- Typography & Hierarchy — size discipline: 5 (20.0/20)
- Color & Contrast — body text contrast (WCAG): 1.22:1 (0.0/30)
- Color & Contrast — primary button contrast: 4.74:1 (10.0/10)
- Color & Contrast — accent discipline: 3 (20.0/20)
- Color & Contrast — surface coverage: 49% dominant (15.7/20)
- Color & Contrast — scheme consistency: dark (10.0/20)
- Spacing & Layout — spacing grid: 6px grid · 83% confidence (29.0/35)
- Spacing & Layout — grid adherence: 5/10 on 6px (12.5/25)
- Spacing & Layout — breathing room: 0.52 density · dense (7.1/25)
- Spacing & Layout — structure & responsive: 2 breakpoints (15.0/15)
- Motion & Polish — motion tokens: 294ms dominant (25.0/25)
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
- Raise body text contrast from 1.22:1 to ≥4.5:1
- Tighten spacing grid adherence from 50% to ≥80%
- Increase breathing room: reduce density from 0.52 to ≤0.45
