/**
 * Creates a class variant function that combines base classes, variants, compound variants, and default variants.
 *
 * @template T - Type of the variant record
 * @param config - Configuration object for creating class variants
 * @returns A function that accepts variant props and returns a combined class string
 *
 * @example
 * ```typescript
 * const button = cv({
 *   base: 'px-4 py-2 rounded',
 *   variants: {
 *     color: {
 *       primary: 'bg-blue-500 text-white',
 *       secondary: 'bg-gray-500 text-white'
 *     },
 *     size: {
 *       sm: 'text-sm',
 *       lg: 'text-lg'
 *     }
 *   },
 *   defaultVariants: {
 *     color: 'primary',
 *     size: 'sm'
 *   }
 * });
 *
 * button(); // => 'px-4 py-2 rounded bg-blue-500 text-white text-sm'
 * button({ color: 'secondary' }); // => 'px-4 py-2 rounded bg-gray-500 text-white text-sm'
 * ```
