   CLAUDPHIC — INNER PAGE STYLESHEET
   Loaded on every page. Every selector here is scoped to a class
   that appears only on inner pages (.page-*, .art-*, .blog-*),
   so the homepage renders byte-for-byte as designed.
   Design tokens are inherited from claudphic.css — nothing is
   redefined, so the two files can never drift apart.
