/*
  THE PUBLIC LIBRARY — www.zorgspace.com/{ar,en,nl}/…

  Layers on /legal/_legal.css (tokens, base type) and /www/_www.css (the ad
  slot, the CTA button), so the library, the landing page and the legal pages
  stay one design system. The pages are generated by
  scripts/build-library.mjs; every class here is one that script writes.

  No script runs on these pages except Google's ad code and /www/ads.js. The
  answers to practice questions open with <details>, which works with
  scripting off, in a reader view, and for a crawler.
