/* ============================================================
   Footer

   Four short groups and a contact block, then a bottom bar.

   What it replaced: fourteen links in four equal columns, eight
   of which 404'd, set in 300-weight #bbb at 24px line height —
   and a cookie-settings button that fell off the bottom of a
   phone screen because the bar it lived in was laid out for a
   desktop row.
