   A calm, premium climate-instrument aesthetic: warm-charcoal surfaces, the
   heat(ember)/cool(frost) duality as the core color language, a serif display
   face (Fraunces) over a refined grotesque body (Hanken Grotesk), subtle
   thermal gradients + grain for atmosphere, and a quiet staggered load.
