Previously, it was unclear that each page type shared a theme-level page template. Within a page, you could view the site-wide template for that page type.
A separate page-level template only exists if changes are made and you expect that particular page to be rendered differently from all other pages of that type.
To clarify this process, we added a button to "Create a custom template" in the Template section of individual pages. By clicking the button, you confirm that you want to edit one specific page's template. A second hyperlink takes you to theme-level template if you would like to make site-wide changes.
Page-level template changes made prior to the addition of this button will display in the Template section of individual pages, where you can make further customizations.
