Outlook — Design Score: 77/100 (grade B)
Strong type hierarchy and text readability (94/100), but primary button is dangerously hard to click (3.47:1 contrast) and layout feels cramped (54/100 spacing).

- Color & Contrast — surface coverage: 36% dominant (9.7/20)
- Color & Contrast — scheme consistency: light (14.0/20)
- Spacing & Layout — spacing grid: 4px grid · 65% confidence (22.8/35)
- Spacing & Layout — grid adherence: 6/12 on 4px (12.5/25)
- Spacing & Layout — breathing room: 0.55 density · dense (4.1/25)

- Motion & Polish — motion tokens: 125ms 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 primary button contrast to ≥4.5:1 WCAG AA
- Increase layout breathing room: target 0.65–0.70 density
- Enforce spacing grid: snap 10+ more measurements to 4px
