/* =============================================================================
   CYNAPSE -- Professional Network layer
   =============================================================================
   Shared styling for Community + Knowledge Center article/detail pages and
   feed listings, built entirely on the existing cw-* design tokens defined in
   cynapse_worldclass.css (loaded before this file on every page that uses
   it). No colors, fonts, or spacing units are reinvented here -- this file
   only adds card/feed/article layout patterns in a LinkedIn-style
   professional-network idiom (rounded cards, avatar-led bylines, chip tags,
   comment threads) on top of the site's actual brand system, so these pages
   look like part of CYNAPSE rather than a separate product.

   Used by: community.html, community_post.html, knowledge_center.html
