   Bendigo Heritage Tender Portal — design tokens
   Drop-in replacement for the app's existing :root variable sheet.
   The app's current names (--primary, --accent, --bg …) are preserved at the
   bottom as aliases, so nothing needs renaming to adopt this sheet.

   Derived from the Bendigo Heritage brand system:
   Navy #112539 (PMS 539) · Gold #A98239 (PMS 7557)
