/* ==========================================================================
   Insights — listing (insights.html) + the three French posts
   (insight-autocomplete / insight-search-sorting / insight-search-filters)
   Layout and page set pieces only: tokens and components come from base.css.
   Signature pieces:
     1. .demo — the article cover as a large live search interface in the post
        hero (typing + suggestions / re-sorting / filtering), backlit by the
        prism light like the hexagon itself.
     2. Living post-card covers: the partials' mini-interfaces replay their
        topic when a card comes into view or is hovered (insights.js).
