/* ══════════════════════════════════════════════════════════════════════════
   CASE STUDIES — shared stylesheet

   The long-form counterpart to The Press Run. A plate on the index tells you
   a project exists in four lines; a case page tells you how it is built and
   how to get into it. Same press: ink ground, paper type, vermilion rule,
   Anton over Cormorant over DM Sans, with IBM Plex Mono doing the labelling.

   No build step. Loaded by every page in /work/ alongside case.js.
