   * THEME COLOR USAGE GUIDE
   * 
   * Always use Nuxt UI CSS variables for primary colors:
   * - var(--ui-color-primary-500) for main primary color
   * - var(--ui-color-primary-400) for lighter shade
   * - var(--ui-color-primary-600) for darker shade
   * 
   * Or use semantic Tailwind classes:
   * - text-primary, bg-primary, border-primary
   * 
   * Never use hardcoded colors like:
   * - purple-500, violet-600, #a855f7
   * 
   * For gradients, use CSS variables:
   * background: linear-gradient(to right, 
   *   var(--ui-color-primary-600),
   *   var(--ui-color-primary-500)
   * );
   *
