/* HeatCoolVerdict. Concept: the site has two temperatures. Ember (too cold, heating) and glacier (too hot, cooling)
   tint the hero, page headers, cards and the verdict gauge; everything else is quiet ink on cool paper.
   Layout: wide airy bands, large rounded surfaces, one reading column for guides with a sticky side rail. */
