   Editorial layout on a strict grid. In a monochrome palette
   the hierarchy has to be carried by space and scale, so the
   rhythm here is deliberate: 120px between major sections,
   32px inside a block, 8px between a label and its value.

   The hero is a sizing tool rather than a photograph, because
   the first question a customer asks is which horsepower fits
   their room, and answering it is more persuasive than a
   picture of a wall unit.
