   cart.css — Shopping cart sidebar + checkout modal
   Self-contained, reusable across sites.
   Depends only on CSS custom properties for theming:
     --cart-accent, --cart-bg, --cart-surface, --cart-border,
     --cart-text, --cart-text2, --cart-danger, --cart-success
   Falls back to sensible defaults if not defined.
