Tailwind Config Extension

// tailwind.config.ts
export default {
  theme: {
    extend: {
      colors: {
        brand: {
          primary: '#2563EB',
          secondary: '#1E40AF',
          accent: '#7C3AED',
        },
        severity: {
          critical: '#DC2626',
          high: '#F97316',
          medium: '#EAB308',
          low: '#3B82F6',
          info: '#6B7280',
        },
        condition: {
          excellent: '#22C55E',
          good: '#84CC16',
          fair: '#EAB308',
          poor: '#F97316',
        },
      },
      fontFamily: {
        sans: ['Inter', 'system-ui', 'sans-serif'],
        mono: ['JetBrains Mono', 'SF Mono', 'monospace'],
      },
    },
  },
};

Best Practices

• Use semantic tokens over raw values
• Maintain consistent spacing rhythm
• Pair shadows with border radius
• Test colors for WCAG contrast

Anti-Patterns

• NO hardcoded hex values in components
• NO inconsistent spacing values
• NO mixing design systems
