v3.0.1

A page whose front matter title matched site.title — which a one-page site's landing
page usually does — rendered <title>Hydrargyri · Hydrargyri</title>. The suffix went on
whenever page.title was set at all, without asking what it was being appended to.

Fixed

• The site name is not appended to itself. Both layouts add the · {{ site.title }}
  suffix only when page.title differs from it; when the two match, the tab, the bookmark
  and the search result read the name once. A page with no title is unchanged, and so is
  every reference page, whose title differs by definition. og:title was never affected —
  poops emits page.title or site.title there, with no suffix.
