   ECONUR — ROOT DESIGN TOKENS
   Single source of truth for colour, type, spacing and motion.
   Swapping in the client's real tokens later MUST be a one-file change here.
   No hard-coded hex/px values may live in templates or component CSS — every
   value references these custom properties. (Master Prompt §3.1, §11)
