/* ============================================================
   /case-studies, and the "More case studies" strip on each case page

   Built on css/system.css. Both come from scripts/build-case-studies.py,
   from one list, so a card and its strip entry always agree. Every card
   leads with the number the case moved, then the story's own headline.
   The whole card is the link: the title's anchor stretches over it.

   One 1240px wrap, like every other page.
