/* =============================================================================
   VOYAIGE — the marketing site's skin.

   NAVY-TO-PAPER. Every value below is a token from the app's own design system
   (.notes/current/design-system.md, switchover 2026-08-31), not an
   approximation of it. The previous skin was #0D1B2A navy on #D8C69F champagne
   gold; both of those tokens were DELETED from the app on 2026-08-31 —
   `champagneGold` and `midnightNavy` are named in the design doc's "Dead" list —
   so the site was showing a palette the product no longer has.

   The three faces are the app's three bundled faces, which are all on Google
   Fonts: Bricolage Grotesque (display), Hanken Grotesk (interface), IBM Plex
   Mono (data and labels). Same reasoning: not "something similar".

   THE ONE STRUCTURAL IDEA: the app puts a dark "stage" card on a paper page,
   and that is the motif this site is built from. The hero is a stage. The
   page around it is paper.
