   for the visitor who wants to read rather than scan. It runs the full width of
   a 1320px container by default, which is roughly 150 characters a line and
   past the point where the eye reliably finds the start of the next one, so it
   takes a measure and centres in the column. Muted, because it sits below
   everything the visitor actually came for. */
