/* ════════════════════════════════════════════════
   CORTEX CARD — Cortex Intellect promo card
   (markup and state logic: templates/includes/cortex_card.html,
   core animation: assets/js/cortex-plexus.js).
   A separate file with ?v= in the headers: /static/ is cached by
   browsers for 7 days and style.css has no version.
   .is-collapsed — card is hidden, the side tab "AI SOLUTIONS" is shown instead
   .is-animated  — state changes after user actions are animated (restored state on page load is not)
   .is-waiting   — first page of the session: hidden until the delay or the consent popups are closed
   .is-entering  — slide-in on the first appearance in the session
   Colors come from the site palette (:root in basic/header.html):
   --thirty_bg cards, --main_bg, the --gradient_* of .main-btn.
