The first chapter <h2> starts right after the title <h1>.
you need some paragraph content following after each heading
Uh oh... Robert Charlton and I have gone round and round on this debate. I think of it like a book author and editor (which I have been for most of my life). Sometimes a section begins right after the main heading and the section has a title. Sometimes there's intro text before the first sub-section.
I would say it's situational, but it must have an internal logic that makes sense.
