/* ==========================================================================
   Best Comfort HVAC - shared stylesheet
   Mobile-first, no frameworks, no preprocessor.

   Design language: "utility instrument". A homeowner lands here with a dead
   furnace and two minutes of patience, so the page is built around real,
   legible status (clock, arrival window, phone) rather than marketing shapes.

   Shape system (locked): interactive things are full-pill, surfaces use the
   --r-sm/md/lg scale, nothing else invents a radius.
   Accent system (locked): --salmon is the only action colour. --ice appears
   only on cooling content, because the palette carries the actual subject
   (heat vs cold), not decoration.
