/*
  TEX Heating & AC
  Native CSS, no framework. Brand tokens carried over from the original site
  (navy ink, heat red/orange, cool blue). Theme follows the visitor's system setting.

  Shape rule: controls (buttons, inputs, chips) = 10px radius. Media + panels = 16px.
  Accent rule: heat red is the only action color. Cool blue appears only where the
  brand's heat/cool split is the point (brand bar, cooling tile, product chips).
