/* dcrypt — carbon paper and cobalt.
   The same family as the other normake.com sites: a pale, slightly green paper,
   near-black ink, one accent. Here the accent is cobalt, the blue of a
   sealed envelope's stamp; it marks every action and the sealed text itself.
   The loud thing on the page is the sealed string, colour-coded by part. */
