   Horizon Gate Coatings & HVAC — hvachorizongate.xyz
   THE DEVICE: the horizon line. Every section is split by one full-bleed rule
   with a marker straddling it — a pale sky field above carrying the heading,
   a warm ground field below carrying the detail. The line recurs at the same
   weight down every page, so the site reads as a landscape rather than a stack.
