 *
 * - If `node` is a component reference (e.g. lucide's `Search`), it is
 *   instantiated with the size className.
 * - If `node` is a valid React element, it is cloned with the size className
 *   prepended so tailwind-merge lets the caller's className win.
 * - Anything else (string, number, fragment, null/undefined) is returned as-is.
