## Ejemplo
```typescript
import { applyTheme } from './apply_theme'
applyTheme({
name: 'dark',
label: 'Oscuro',
colors: themeConfigToColors(darkThemeConfig)
})
```
## Notas
Función impura (modifica el DOM). Mapea cada key de ThemeColors a una CSS variable. Temas oscuros (dark, midnight, sunset) añaden clase `dark` al root.
