/**
 * 1. Custom Post Type has archives and the slug is rewritten.
 * In this case a visit to /post-type-name will use archive-$posttype.php, $archive.php, index.php.
 * Pagination will work by default assuming $rewrite[ 'pages' ] is also true (default).
 * It's not possible to create a landing page called /post-type-name as the archive page controls the template hierarchy.
