Not every published page needs a place in the header. This page uses show_in_navigation: false, so it stays out of the main navigation and the automatic Previous/Next sequence.

It is still reachable through links and the theme tag, where it appears beside opted-in pages and dated posts.

Navigation visibility is a presentation setting, not access control. Do not place private content in a generated site and rely on an absent menu link to protect it.
