How it works?

        // We can declare some styles if need
        // We will can use it as single-usage or as collections
        $styles = [
            'bootstrap5' => 'https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/css/bootstrap.min.css'
        ];

        // And some scripts
        $scripts = [
            'axios' => 'https://cdnjs.cloudflare.com/ajax/libs/axios/1.4.0/axios.min.js',

        $ac = new AssetsCollectionGeneric($scripts, $styles);
        $ac->setScript('myscript', 'url');
        // We can add scripts by hands, not in array

        // Create new collection of assets
        $ac->setCollection('standard', ['bootstrap5', 'jquery', 'myscript'], ['axios'], ['bootstrap5', 'mystyle']);

        // After creating Assets collection we can create something like this:
        // $webPage->applyAssetsCollection('standard') for example in controller;
        
        // WebPage object what epresents web page
        $webPage = new WebPageGeneric($viewTopology, $ac);
        // Set style from CDN

        $webPage->setPageTitle("My page Title");
        $webPage->setKeywords(["one","two","three"]);
        $webPage->setKeywords("four");
        $webPage->setKeywords("six,seven");

        // Why? Now we will can use in our Twig template that variables:
        // {{ base }},{{ js }},{{ css }},{{ fonts }},{{ images }},{{ theme }},{{ libs }} - URL Path for folders
        // {{ scripts_header }}, {{ scripts_footer }}, {{ styles }}, {{ importmap }}
        // {{ title }}, {{ keywords }}, {{ header }}, {{ description }} etc...

        // Get the Twig adapter (Core\Interfaces\ViewAdapterInterface)
        $viewAdapter = new TwigAdapter($twigConfig, $viewTopology, $webPage, $request, $response, $cache, $logger);

        // Get the view (Core\Interfaces\ViewInterface)
        // Also, you can overwrite here template paths and ResponseInterface
        $view = $view->getView();

        // Now we can use View
        $vars = [
            'one' => 'one var',
            'two' => 'two var'
            ];

        $view->assign('three', 'three var');

        // Set the layout, variables, response code, headers, cache ttl in sec
        // $response is Psr\Http\Message\ResponseInterface
        $response = $view->render("layout.tpl", $vars, 200, [], 0);

        // Now we can use PSR $response
        $response->getStatusCode();
        $response->getBody()
