/* ============================================================
   Elcano public site — Insights hub + article pages
   ============================================================
   Loaded AFTER site.css on /content and every /content/<slug>
   article page. Defines two things:

     1. The Insights index grid (hub hero + responsive cards).
     2. The article reading layout (centered ~680px prose column,
        styled headings/lists/quotes, pull-stat treatment, CTA,
        back-to-Insights link).

   Every color/font references a token from tokens.css so both
   dark (default) and light mode work. No hard-coded hex values.
