/* ==========================================================================
   Vantage Acquisitions — shared page stylesheet
   --------------------------------------------------------------------------
   ONE design system for every page that is not compiled by Tailwind.
   Linked by: book, thank-you, privacy, terms, proposal.

   The :root block below is copied VERBATIM from build/input.css so these
   pages and the Tailwind pages (index, websites) cannot drift. Do not edit a
   token here without editing it there. check-design.py asserts they match.

   Written 2026-08-31 to retire the July 31 Fraunces/Inter system, which had
   its own tokens, its own type, and the retired checkmark logo, and which
   made five pages of this site look like a different company.
   Full rules: DESIGN.md at the site root.
