## Retro CSS Architecture

Organize CSS for 8-bit components using custom properties, pixel fonts, and responsive patterns.

### Required Import

All 8-bit components must import the retro stylesheet:

```tsx
import "@/components/ui/8bit/styles/retro.css";
```

### Pixel Font

Use "Press Start 2P" for authentic 8-bit typography:

```css
.retro {
  font-family: "Press Start 2P", system-ui, -apple-system, sans-serif;
  line-height: 1.5;
  letter-spacing: 0.5px;
}
```

Apply via class or font variant:

```tsx
<Button className="retro">START GAME</Button>

// or via font prop
<Button font="retro">START GAME</Button>
```

### Pixelated Images

For sharp pixel art images:

```css
.pixelated {
  image-rendering: pixelated;
  image-rendering: crisp-edges;
}
```

```tsx
<Image src="/pixel-art.png" className="pixelated" />
```

### Dark Mode Colors

Use semantic color names with dark mode variants:

```tsx
<div className="border-foreground dark:border-ring" />
<div className="bg-foreground dark:bg-ring" />
```

### Responsive Pixel Sizes

Use consistent pixel values for retro feel:

```tsx
{/* Standard pixel sizes */}
<div className="size-1.5" />      {/* Corner pixels */}
<div className="h-1.5 w-3" />     {/* Shadow segments */}
<div className="border-y-6" />     {/* Card borders */}

{/* Mobile considerations */}
<div className="h-[5px] md:h-1.5" />
```

### CSS Organization

Keep retro-specific styles in `components/ui/8bit/styles/retro.css`:

```css
/* Import pixel font */
@import url("https://fonts.googleapis.com/css2?family=Press+Start+2P&display=swap");

/* Font class */
.retro {
  font-family: "Press Start 2P", system-ui, -apple-system, sans-serif;
  line-height: 1.5;
  letter-spacing: 0.5px;
}

/* Image handling */
.pixelated {
  image-rendering: pixelated;
  image-rendering: crisp-edges;
}
```

### Component-Level CSS

Use Tailwind utilities for component-specific styling:

```tsx
<div
  className={cn(
    "relative border-y-6 border-foreground dark:border-ring",
    "rounded-none active:translate-y-1 transition-transform",
    className
  )}
/>
```

### Key Principles

1. **Import retro.css** - Required for all 8-bit components
2. **Pixel font** - Use "Press Start 2P" for authentic look
3. **Pixelated images** - Apply `image-rendering: pixelated` to sprites
4. **Consistent sizing** - Use fixed pixel values (1.5, 3, 6px)
5. **Dark mode** - Use semantic colors with `dark:` prefix
6. **rounded-none** - Remove all border radius for retro feel
7. **Tailwind first** - Use utilities before custom CSS
