I built up a lot of expectation that this article was going to be self-referential and link to a hidden well of info. At the very least it ought to link to one example of such an article so we know you aren't describing something theoretical.
I don't feel bad for being unable to conceive of the "navigation bar" containing a link to the page's real content. That's the most effective camouflage possible.
I developed a writing format that I call an “iceberg article”:

… which qualifies as an inverted pyramid but with some additional attributes.
