The node a page or section is being created for.
Whether the content is for a page.
This template is called by importing stylesheets after any content of a page or section, but before any subsections. It applies html.content.post.mode to $node, then calls html.content.post.custom. If the $page parameter is true, then this template is being called on an output page. Otherwise, it is being called on a section within a page.
