/* ============================================================
   "Summera" — the AI summary overlay behind a feed card.

   Structure mirrors the KPI explainer (.kx-*) so the two AI panels in the
   product read as one system; the tokens are the shared --brand-* ones that
   feed-card.css and panel-head.css use, so this inherits the site palette
   rather than carrying a second one.

   Driven by core_data/js/feed_summary.js.
