   Eneon Technologies — site styles
   Brand colours come from the Eneon logo: deep navy (#003D92), electric blue
   (#068CE3) and cyan (#0DBDF1). The visual language (navy, two-tone white/cyan
   headings, cyan ring icons, circuit traces) follows the Eneon service flyers.
   Dark is the default theme. Change tokens here, not in components.
