/* =========================================================================
   Whisper — version two, in the Interface Craft manner.

   The same words as index.html, arranged the opposite way. Where v1 is a wide
   page that changes colour under you and holds its objects in pills, this one
   is a single narrow column on one warm near-black ground the whole way down.
   Its rules are:

   · one measure, centred, about 62 characters — nothing runs wider except the
     artefact rows, which are the only things allowed to breach it
   · a serif for anything that is a statement (headings, quotes, figures) and
     the sans only for reading text and labels
   · type stays small: the largest thing on the page is 50px, not 90
   · sections are separated by a short centred hairline, not by a colour change
   · no ground system, no floating bar, no parallax — the restraint is the
     design
   ========================================================================= */
