Use second- and third-level headings, respectively. When rendered
in GitHub, `#` is an `<h1>`, which should actually be the most pro-
minent heading on the page; in this case GitHub's own headings sho-
uld take precedence, so ours should start at `<h2>` essentially.

Use "public" with "max-age" instead of Expires, as "max-age" is always
preferred if it's present. Note: setting "public" doesn't make the
resource "more cacheable", but it is just more explicit.
