Single article page.

Loaded after theme.css so it can override the stock blog-single styles, whose
fixed-height banner clipped long headlines and whose avatar relied on a
translateY(-48px) hack.

Keeps Open Sans and the brand navy rather than introducing a display face:
one page is not the place to fork the site's typography.
