   Design tokens grounded in the brief: blue/white base (client's
   own palette call), copper drawn from the real brass fittings
   and copper pipe in their work photos. 60/30/10: bg (60) / petrol
   blue (30) / copper (10), WhatsApp green reserved only for chat
   actions so it keeps its own recognition value.
