    $fallbacks = Collection::wrap($classes)
        ->mapWithKeys(fn($partial, $fallback) => is_int($fallback) ? [$partial => Str::of($partial)->before("-")->when(Str::contains("-", $partial), fn($string) => $string->append('-'))->__toString()] : [$fallback => $partial])
        ->toArray();

    return $this->class($fallbacks);
