/* ==========================================================================
   collection.css - blog posts (/blogs) and case studies (/case-studies)
   --------------------------------------------------------------------------
   Both sections share this sheet. It carries ONLY what is new to them:

     - the card grid on the two index pages
     - the eyebrow + date line in an article hero
     - the facts panel at the top of a case study

   The two-column article layout itself (.service-layout, .service-body,
   .service-aside, .service-cta, .related, .breadcrumb) is NOT duplicated here.
   Article pages load service.css alongside this file - see articleMeta() in
   worker.js - because that layout is identical to a service page's and there
   is no reason to maintain a second copy of it.
