   Tokens mirror the Momentum brand (void/gold/cream · Cormorant + Montserrat).

   transform/opacity, driven by state app.js already makes. Reveal-hiding only
   under html.js-polish + prefers-reduced-motion: no-preference (safety
   inversion: no JS / reduced motion => everything simply visible).
