[Design System] Validate that code and styles use official design tokens instead of hard-coded values. Use when (1) reviewing CSS/SCSS/Tailwind/styled-components for hard-coded colors/spacing, (2) checking SwiftUI/UIKit for raw color/font values, (3) auditing Unity styles for magic numbers, (4) enforcing design system compliance, (5) user asks to 'check design tokens', 'validate tokens', 'find hard-coded values', or 'audit design system usage'.
