## Class Organization
Organize classes in this order:
1. Layout (display, position, flex, grid)
2. Sizing (width, height, max-width)
3. Spacing (padding, margin, gap)
4. Typography (font, text)
5. Colors (background, text color, border color)
6. Borders (border, rounded)
7. Effects (shadow, opacity)
8. Transitions

## Responsive Design
```html
<!-- Mobile-first approach -->
<div class="
  flex flex-col gap-4 p-4
  sm:flex-row sm:gap-6
  lg:gap-8 lg:p-8
">
  <aside class="
    w-full
    sm:w-64
    lg:w-80
  ">
    Sidebar
  </aside>
  <main class="flex-1">
    Content
  </main>
</div>
```

## Dark Mode
```html
<div class="
  bg-white dark:bg-gray-900
  text-gray-900 dark:text-white
  border border-gray-200 dark:border-gray-700
">
  <p class="text-gray-600 dark:text-gray-400">
    Muted text
  </p>
</div>
```

## Component Variants
```tsx
import { cva, type VariantProps } from 'class-variance-authority';

const button = cva(
  'inline-flex items-center justify-center rounded-md font-medium transition-colors focus:outline-none focus:ring-2 disabled:opacity-50',
  {
    variants: {
      variant: {
        primary: 'bg-blue-600 text-white hover:bg-blue-700 focus:ring-blue-500',
        secondary: 'bg-gray-100 text-gray-900 hover:bg-gray-200 focus:ring-gray-500',
        ghost: 'hover:bg-gray-100 focus:ring-gray-500',
      },
      size: {
        sm: 'h-8 px-3 text-sm',
        md: 'h-10 px-4',
        lg: 'h-12 px-6 text-lg',
