/**
 * Merges one or more Tailwind CSS class name strings or conditional objects
 * into a single, de-duplicated class string.
 *
 * Internally this runs `clsx` first (which handles conditional objects and
 * arrays) and then passes the result through `tailwind-merge` so that
 * conflicting utility classes are resolved correctly (e.g. `p-2 p-4` → `p-4`).
 *
 * @param inputs - Any mix of strings, objects, or arrays accepted by `clsx`.
 * @returns A merged Tailwind class string with conflicts resolved.
 *
 * @example
 * cn("px-4 py-2", isActive && "bg-blue-500", "hover:bg-blue-600")
 * // → "px-4 py-2 bg-blue-500 hover:bg-blue-600"  (when isActive is true)
