   FREE-PAPERS HUBS (exams/templates/exams/papers/*)
   ------------------------------------------------------------
   Plain CSS, no Tailwind. Sits on top of course-pages.css (cs-kicker,
   cs-compare, cs-seo, cs-section-*) and the design-system tokens
   (--text-*, --space-*, --pad-x, .sec-solid, .sec-blue, .btn-cobalt).
   Every selector is prefixed pp- . No pills, no gradients, no icons:
   rules, spacing and type do the work.
