   DESIGN TOKENS - Colors (OKLCH)

   Dark Mode Guidelines:
   - Never use pure black, use ~90-94% black (6-10% lightness)
   - Surface layers need 4-6% lightness difference (double light mode)
   - Surfaces get LIGHTER as they elevate
   - Text: Headings 85-90%, Body 70-75%, Secondary 55-60%, Disabled 40-45%
   - Accent: Use 300-400 range for dark mode primary
