/* ==========================================================================
   Concept A: "The Broadsheet"

   Newspaper editorial. Columnar feel, serif body, big condensed headlines,
   thin rules, date-stamp metadata. Like a well-designed section front from
   a serious paper. Light mode is warm newsprint; dark mode is ink-on-slate.
