<!doctype html> </!doctype> OT: is there a reason to open/close the DocType at the beginning of the homepage source?

  No. It's not in the spec, and in almost 30 years of web development, this might be the first time I've ever seen someone use a closing tag for it.

    It's also not a tag, but an SGML (?) directive (specifically a https://en.wikipedia.org/wiki/Document_type_definition https://en.wikipedia.org/wiki/Document_type_definition) and so it is in fact invalid to produce a closing tag.

      HTML5's HTML syntax is no longer SGML-based. It's still invalid but no longer because of anything related to SGML; now it's simply because the HTML5 spec says so.
