   Oakmont HVAC Building Services — oakmonthvac.xyz
   One stylesheet. No framework, no build step.

   LAYOUT: commercial first, built for legibility. A white top bar — wordmark
   left, links right, the current page in rose with a small caret beneath,
   phone and a rose CTA. The hero photo sits in a frame offset over a rose
   block. The signature component is a three-generation refrigerant lineage
   (R-22 → R-410A → A2L) with a status and a plain "what it means" for each.
   One typeface: Atkinson Hyperlegible, chosen for reading clarity.
