Rebuild the Blog Architecture

Rebuild the blog page from the brief: complete document (doctype, html lang, charset, title); an <hgroup> wrapping the page <h1> and a subtitle (<p> or <span>); exactly one <h1>; heading levels never skip; a comments region as <section aria-labelledby="…"> whose label is a real heading inside it; and a reader comment as a nested <article aria-labelledby="…"> inside the post article. Content is yours — structure is graded.
