Claude — Design Score: 94/100 (grade A)

claude.com · 94/100 · grade A · top 1% of 313 measured design systems · measured live — not guessed

Typographic and color systems are pristine; spacing rhythm has small gaps—fix grid adherence to lock visual coherence.

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

Audit and snap all spacings to 4px base unit
Validate type ladder jump at smallest step (1.07× gap)
Document breathing room rules in spacing system
