   COMPOUND — editorial wealth-building magazine
   Design language mirrors GQ: centered serif masthead, category kickers,
   serif editorial headlines, "Most Read" side rails, "Read More" bottom rails,
   clean black-on-white canvas with a single deep-green brand accent.
   (Working brand name "COMPOUND" is a placeholder — swappable site-wide.)
