/* ============================================================
   Actualization AI shared shell: design tokens plus the header
   and footer that <site-header> and <site-footer> in js/site.js
   render. EVERY page loads this one, the homepage included, so
   the navigation cannot drift between them.

   It deliberately carries no global resets and no body rules,
   because index.html is a Design Component with its own inline
   typography and must not be restyled by loading the shell.
   Those globals live in css/site.css, which the non-homepage
   pages load alongside this file.
