Actually it shows you don't get HTML... or what the TITLE tag is or what HEAD is for. That's not your fault, 'cause damn it's poorly documented and from the start assumed people knew things like logical document structure. Probably because TBL's original audience for this was folks writing science papers at CERN and other institutions.
Anything inside <head> is NOT actually considered part of the page content. It is instructions for browsers to ENHANCE the page content.
the TITLE tag is for text that will be used to link back to the current page, or to describe the tab/window. It is NOT where you go looking for the page title or site title, it's where you tell the browser or other user-agent what text to show on a back-link for something like a search engine or generated link, or the window frame / tab.
What you just made up tags for has NOTHING to do with ANYTHING that belongs inside HEAD.
Your "section" is kinda pointless, but the real relationship would be the H1 and H2.
And it's not silly for them to be called that, as that's what they're called in English. The "heading 1" describes the document, whilst heading 2's describe major subsections of that document.
Think of the H1 as being like the title of a newspaper or book, where it appears on each and every page. It might be bigger atop the home-page and smaller with the page number on subpages, but it's still that same depth heading. It's only replicated across pages to tie the document together. Web pages are supposed to be thought of in the same mindset.
Did you not learn this in grade school? 'Cause it seems like nobody else learned this in grade school. HTML was quite literally created as a 1:1 of proper grammar/structural rules of the English language as used in things like scientific papers, whitepapers, technical documents, legal documents, and business letters. The five heading depths being a part of that, with H6 thrown in as "overkill". (If your content itself actually hits H6, there's probably something wrong with your document)
Also welcome aboard, be warned this is the firing line. No toxic positivity allowed!
