/* ═══════════════════════════════════════════════════════════════
   IRIDESCENCE, properly.

   A fired vessel does not sit under one flat light. The whole page is
   treated as a dark glazed surface with an oil-slick sheen moving over it:
   a soft colour mesh on the ground, gradient edges on the objects that
   matter, and a sweep on the things you touch.

   Three rules kept throughout:
     · every gradient stop is pre-solved for contrast, so nothing here can
       make text illegible
     · near-black gradients BAND in 8-bit, so a grain layer sits over the
       whole ground
     · only transform and opacity animate
