/* ═══════════════════════════════════════════════════════════════════════
   The Journey Into the Holy of Holies

   Built entirely on the Broadsheet design system's own tokens (--color-bg,
   --color-text, --color-accent, --color-accent-2, --font-heading) and its
   existing motion engine ([data-scrub], [data-reveal], [data-ink-ground] —
   see embassy-motion.js). No new colours, no new animation engine — this
   file is composition and choreography on top of what already exists.

   The whole journey lives in ink (--color-text as background) until the
   Holy of Holies, which is the one deliberate inversion: the page turns to
   paper-light (--color-bg) for the climax and stays there through the final
   invitation. That inversion IS the "dramatic environment change" — no new
   colour required to earn it.
