   Qyverix — subpage system (Nov 2026)
   Services, locations, case studies, journal, legal and contact share one
   editorial structure, drawn with the homepage tokens from css/site.css, so
   every page lives in both worlds: Foundry (ink) and Press (paper).
   Class names are the long-standing template ones (qx-case-page__*, qx-blog__*,
   qx-article__*, qx-contact-page__*): templates needed no markup rewrite.
