Check if page exists, is published and has content

 There are 2 page settings. Both are set.

  1. "featured_page_1" is set to "some-page", a published page with content.
  2. "featured_page_2" is set to "hidden-page", a hidden page with content.

Hidden pages are like non-existent pages, except they can still be selected in the theme settings, so you must use unless == blank to make sure the page exists and is published, before you access it.
