   BlueStone HVAC Finishes — bluestonehvac.xyz
   One stylesheet. No framework, no build step.

   DARK BY DEFAULT. This is the only dark site in this workspace and it is a
   deliberate exception to the usual "light theme for business sites" rule —
   see BRIEF.md. Every text/background pair below was checked against WCAG AA.

   LAYOUT: a two-column reader. On desktop the left column sticks while the
   right column scrolls past it, so the argument of a section stays on screen
   while its detail moves. The nav is a thin rail across the top of that
   left column.
