Vapi — Design Score: 77/100 (grade B)
Strong dark-mode typography & motion polish (B grade), but color feels flat & spacing grid isn't fully locked—risks visual hierarchy collapse at scale.

- Typography & Hierarchy — heading line-height: 0.90 (6.7/10)
- Typography & Hierarchy — size discipline: 5 (20.0/20)
- Color & Contrast — body text contrast (WCAG): 18.44:1 (30.0/30)
- Color & Contrast — primary button contrast: 21.00:1 (10.0/10)

- Color & Contrast — surface coverage: 23% dominant (3.2/20)
- Color & Contrast — scheme consistency: dark (10.0/20)
- Spacing & Layout — spacing grid: 8px grid · 78% confidence (27.3/35)
- Spacing & Layout — grid adherence: 8/12 on 8px (16.7/25)
- Spacing & Layout — structure & responsive: 2 breakpoints (15.0/15)
- Motion & Polish — motion tokens: 150ms dominant (25.0/25)
- Motion & Polish — choreography: 10 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
- Tighten heading line-height from 0.90 to 1.05–1.15
- Flatten type ladder: replace 2.67× jump with 1.5–1.6×
- Add secondary surface accent color to 40–50% coverage
