Mathematical type scales, strict 8px spacing tokens, WCAG AA/AAA contrast, and complete state matrices for every UI component. Creating a semantic CSS custom-property token architecture for a new web app, SaaS dashboard, or documentation portal Fixing inconsistent spacing, arbitrary font sizes, and unreadable low-contrast text across dark and light themes Defining complete interactive states (default, hover, focus-visible, active, disabled, loading, empty, error) for UI components Auditing layouts for keyboard accessibility, touch-target sizing (>= 44x44px), and responsive breakpoint behavior Separate primitive tokens (raw hex colors, pixel steps) from semantic tokens (--bg-canvas, --bg-surface, --text-primary, --border-subtle). Restrict all padding, margin, and gap values to the 4px/8px spatial scale (4, 8, 12, 16, 24, 32, 48, 64px). Enforce WCAG AA contrast minimums: >= 4.5:1 for body copy, >= 3.0:1 for large headings and interactive borders. Cap line length for reading comfort at 60-75 characters (max-width: 65ch) and pair tight heading line-height (1.15) with relaxed body line-height (1.6). Compute nested border-radius mathematically: Rinner = max(2px, Router - padding) so conc
