/* ==========================================================
   NZ Tax Adventure — restyled to consume hub design tokens
   (Kauri & Paua palette from /styles/tokens.css).

   Token usage (chrome):
     --paper   page + section background
     --ink     primary text, borders, dark accents
     --deep    secondary text
     --rule    dashed dividers, subtle borders
     --kauri   primary accent (active states, "money-in")
     --paua    secondary accent (links, "money-out", compare)
     --manuka  warning / emphasis ("dodge", villain, highlight)

   Diagram semantic colours (--money-in, --money-out, --dodge,
   --gold, --villain) are aliased to the new tokens so the
   cartoon pipes still read as IN / OUT / DODGE without
   re-authoring every SVG rule.
