/* Components for the inner pages (About, Work, Work With Me, Thinking,
   Contact, case study and article templates) and the new home sections.
   Everything sits on the site's existing foundation: Poppins, black and deep
   charcoal surfaces, warm off white chapters, thin rules, large type.

   Five systems:
     A  monumental typography   .page-hero, .t-hero, .cta-band
     B  numbered rows           .rows / .row
     C  editorial visuals       .figure, .work-index, .story
     D  data and proof          .facts, .proof
     E  editorial lists         .list, .breadth (grid variant)

   Elements whose text is a placeholder for content still to come carry the
   class .ph (and, where useful, data-placeholder="what-goes-here"). */
