   Automotive palette: deep teal brand + warm amber accent. Distinct from the
   green / navy+orange / steel+copper / royal-blue / sandstone / racing-red
   trades sites already used. Variable NAMES match _shared/base.css; only values
   changed. Contrast verified for AA (see arvu-auto.design.json). */
