Component Example (React)

interface ButtonProps {
  variant?: 'primary' | 'secondary' | 'ghost';
  size?: 'sm' | 'md' | 'lg';
  loading?: boolean;
  disabled?: boolean;
  children: React.ReactNode;
}

function Button({ variant = 'primary', size = 'md', loading, disabled, children }: ButtonProps) {
  return (
    <button
      className={`btn btn-${variant} btn-${size}`}
      disabled={disabled || loading}
      aria-busy={loading}
    >
      {loading ? <Spinner /> : children}
    </button>
  );
}
