Accessibility: author name in footer causes heading level confusion

[Seirdy]

Users of assistive technology often navigate by headings.

The author name in the footer is an h4 element. If the last heading in the article is h3, this makes the author appear to be a sub-category of the last section in the article when navigating by headings. Should the last greater-or-equal heading in the article be an h2, this would cause a jump from h2 to h4, which is a common accessibility issue and confusing to assistive-technology users.

My suggested fix is to make the author name h2 so it's clearly a top-level item below the page title.
