   Clearview HVAC Coatings — clearviewhvac.xyz
   One stylesheet. No framework, no build step.

   LAYOUT: homes and businesses equal; light, airy, bay-fog calm. A white
   bar with links on the right; a teal chevron sits before the current page.
   The home page opens with the headline and a photo, then a strip of the
   three routes to cooling a building that never had it. The signature
   component is that comparison in full: three routes, five questions,
   dot ratings with the words beside them. One typeface: Fira Sans.
