 * Site footer (shared/_footer): a frosted sheet across the full width of the screen, under the
 * page card, in the same light palette. Navy text and gold-deep headings. Its content keeps to
 * the header's width, from the header logo's line to the Sign in line (--site-gutter and
 * --site-inset, set in site.css). Phones: brand, the two link groups side by side, then contact.
 * 768px: brand on top, three groups below. 1200px: four columns. From 768px the columns size to
 * their content and spread out, so the last one ends on the Sign in line.
