/* Novastacks blog article + index, revamp skin (2026-10).
   A scoped layer over Blog Template v3: every v3 class (article-wrap, article-layout, article-hero,
   article-sidebar, article-contents, article-prose, key-takeaways, article-faq, service-cta,
   article-related ...) is kept so validate-blog-template.py and validate-eeat.py still see the
   skeleton. Activated by <body class="... rv-page rv-article">; without that class nothing here applies.
   Requires revamp.css (tokens, linen texture, header/footer restyle) loaded first. */
