* Give the article title a larger, heavier font than any heading.
It was strange that the title was 20px regular while the
h1 section headings were 24px.
* Move the author attribution to the top of the page.
Author at the bottom, like a signature, may make sense for blog posts,
but I think it makes less sense for articles.
* Fix the spacing around author lines. Each author line is a <p>
and the intent seemed to be to cut the vertical space between them
but that wasn't working.
* Give the table of contents a title, to make clearer what it is.
Do not show table of contents in printouts.
