The library uses CSS custom properties for theming. The design system includes:

Colors - Primary, secondary, accent, destructive, muted, and semantic colors

Spacing - Consistent spacing scale (0.5rem increments)
Radius - Border radius tokens from sm to full

// Usage in styles

  background: ${bdTheme('hsl(0 0% 100%)', 'hsl(0 0% 10%)')};
