## Ejemplo

```tsx
<Card>
  <CardHeader>
    <CardTitle>Título</CardTitle>
    <CardDescription>Descripción</CardDescription>
  </CardHeader>
  <CardContent>Contenido</CardContent>
  <CardFooter>Footer</CardFooter>
</Card>

{/* Dashboard dark — sin bordes */}
<Card variant="borderless">
  <CardContent>Widget sin marco</CardContent>
</Card>

{/* Completamente transparente */}
<Card variant="ghost">
  <CardContent>Sin fondo ni borde</CardContent>
</Card>
```

## Notas

Sistema de slots via data-slot attributes. Card detecta automáticamente la presencia de CardFooter y ajusta el padding. Exporta 7 subcomponentes composables.

Las variantes `borderless` y `ghost` eliminan el `ring-1` del borde por defecto. `ghost` además hace el fondo transparente. Alternativa con CSS global: `[data-slot="card"] { --tw-ring-opacity: 0; }` o `[data-variant="borderless"] { ring: 0 }` via `data-variant` attribute expuesto.
