/* Paper Trail tokens, carried over from culmentech.com as real custom
   properties rather than the marketing site's inline hexes — see the plan's
   "Carrying over the Paper Trail tokens" section for why: no dc-runtime here
   to force that pattern, and a back office with tables/forms/states needs
   the discipline a stylesheet gives.

   Hard rules that this file exists to enforce (see plan §Screens):
     - no red anywhere, including "failed" and "opted out"
     - marker (#80C0C0) is a highlighter — ink text ON it, never AS text
     - marker is never used for focus rings
     - cards: 1px line border, 2px radius, no shadows
