/* ═══════════════════════════════════════
   AnalyzAI — Biomarker reference pages (article body)
   ═══════════════════════════════════════

   Scope: the article body only. Header/footer live in site-chrome.css.
   Tokens come from brand.css; buttons and base table styles from components.css.

   Constraints: mobile-first, lightweight, no animation. There will eventually be
   hundreds of these pages and the traffic is mostly mobile search.
