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
- Repair body text contrast to 4.5:1 minimum
- Expand weight spread to 2 distinct roles
- Enforce 8px grid compliance to 100% of spacings
