/* =====================================================================
   Mavion — shared design system
   ---------------------------------------------------------------------
   Single source of truth for every page outside the homepage. The home
   page (index.html) carries an identical copy inline for its critical
   path; this file mirrors that system 1:1 and adds the components the
   content-grid / network / info pages need (page heads, filter chips,
   the unified story-card grid). Pull it in with:

     <link rel="stylesheet" href="/mavion.css?v=1" />
     <script src="/mavion-chrome.js?v=1" defer></script>
     <script src="/mavion-cards.js?v=1" defer></script>

   Spec: premium, cinematic, dark-mode editorial. Hierarchy from scale,
   whitespace, and a serif/sans/mono type system — never bright colour.
