/* Cairnea — cairnea.com
   Corporate parent page. KinDash leads; the Android apps are a second line, and
   the layout says so before the words do.

   The promise is "calm, accessible", so the page argues it by being it rather
   than claiming it: 18px base text, generous leading, a short measure, large
   targets, one accent colour, and no motion at all. Restraint is the design.

   Palette is early-morning kitchen light — a cool pale ground with one warm
   ochre, the colour of a lamp on at 7am. Deliberately not the warm-cream-and-
   serif or the dark-mode-with-acid-accent that every software company uses. */
