/* Data Driven Decisions website: the design system (docs/REDESIGN-PLAN.md, PR 2), one look for the studio home and
   the three apps, in English and in French (site/fr/). "Newsprint meets highlighter": paper, ink, the app's accent.
   Every colour is a token on :root; each page's <body> class (studio, app-brickography, app-marblecodex,
   app-fakeorfact) sets the app's paper, ink and accent, and the dark "night edition" follows the phone's
   setting (prefers-color-scheme). Headings are Noto Serif (self-hosted, assets/fonts/, SIL Open Font License),
   text the system sans. Every animation sits inside prefers-reduced-motion: no-preference; tools/check_site.py
   enforces that, the 30 KB budget of this file and the 45 KB budget of a font. */
