/* ===========================================================================
   Diabeasy — public site
   ---------------------------------------------------------------------------
   The visitor is usually mid-search: "hba1c 8.4 meaning", "creatinine high
   in diabetes", or a daughter looking for something to help her father. They
   arrive anxious and they arrive on a phone.

   The organising idea is TRANSLATION. A lab report is a wall of codes and
   asterisks that means nothing to the person holding it. The whole site is
   built around showing that wall turning into a sentence — the .render block
   below is that motif, and it repeats down the page rather than being a
   one-off hero trick.

   Palette and type continue the portal (indigo / sage / ochre, Baloo 2 +
   Hind) so arriving at the product feels like the same place. The public
   site is allowed more air and bigger type; nothing else changes.
