/**
 * @file
 * Zen theme's implementation to display the basic html structure of a single
 * Drupal page.
 *
 * Variables:
 * - $css: An array of CSS files for the current page.
 * - $language: (object) The language the site is being displayed in.
 *   $language->language contains its textual representation. $language->dir
 *   contains the language direction. It will either be 'ltr' or 'rtl'.
 * - $html_attributes: String of attributes for the html element. It can be
 *   manipulated through the variable $html_attributes_array from preprocess
 *   functions.
 * - $html_attributes_array: Array of html attribute values. It is flattened
 *   into a string within the variable $html_attributes.
 * - $rdf_namespaces: All the RDF namespace prefixes used in the HTML document.
 * - $grddl_profile: A GRDDL profile allowing agents to extract the RDF data.
 * - $head_title: A modified version of the page title, for use in the TITLE
 *   tag.
 * - $head_title_array: (array) An associative array containing the string parts
 *   that were used to generate the $head_title variable, already prepared to be
 *   output as TITLE tag. The key/value pairs may contain one or more of the
 *   following, depending on conditions:
 *   - title: The title of the current page, if any.
 *   - name: The name of the site.
 *   - slogan: The slogan of the site, if any, and if there is no title.
 * - $head: Markup for the HEAD section (including meta tags, keyword tags, and
 *   so on).
 * - $default_mobile_metatags: TRUE if default mobile metatags for responsive
 *   design should be displayed.
 * - $styles: Style tags necessary to import all CSS files for the page.
 * - $scripts: Script tags necessary to load the JavaScript files and settings
 *   for the page.
 * - $skip_link_anchor: The HTML ID of the element that the "skip link" should
 *   link to. Defaults to "main-menu".
 * - $skip_link_text: The text for the "skip link". Defaults to "Jump to
 *   Navigation".
 * - $page_top: Initial markup from any modules that have altered the
 *   page. This variable should always be output first, before all other dynamic
 *   content.
 * - $page: The rendered page content.
 * - $page_bottom: Final closing markup from any modules that have altered the
 *   page. This variable should always be output last, after all other dynamic
 *   content.
 * - $classes: String of classes that can be used to style contextually through
 *   CSS. It should be placed within the <body> tag. When selecting through CSS
 *   it's recommended that you use the body tag, e.g., "body.front". It can be
 *   manipulated through the variable $classes_array from preprocess functions.
 *   The default values can contain one or more of the following:
 *   - front: Page is the home page.
 *   - not-front: Page is not the home page.
 *   - logged-in: The current viewer is logged in.
 *   - not-logged-in: The current viewer is not logged in.
 *   - node-type-[node type]: When viewing a single node, the type of that node.
 *     For example, if the node is a Blog entry, this would be "node-type-blog".
 *     Note that the machine name of the content type will often be in a short
 *     form of the human readable label.
 *   The following only apply with the default sidebar_first and sidebar_second
 *   block regions:
 *     - two-sidebars: When both sidebars have content.
 *     - no-sidebars: When no sidebar content exists.
 *     - one-sidebar and sidebar-first or sidebar-second: A combination of the
 *       two classes when only one of the two sidebars have content.
