/* ════════════════════════════════════════════════
   CORTEX EXIT BANNER — full-screen Cortex Intellect banner
   (markup: templates/includes/cortex_exit_banner.html,
   triggers, focus, scroll lock and the core animation: assets/js/cortex-exit-banner.js).
   A separate file with ?v= in the headers: /static/ is cached by
   browsers for 7 days and the name has no hash.
   [hidden]  — closed (display: none)
   .is-open  — shown, the fade-in / fade-out runs on this class
   html.cortex-exit-lock — page scroll is blocked while the banner is open
   Colors come from the site palette (:root in basic/header.html), as on the small card
   (cortex-card.css): --thirty_bg panel, --main_bg, the --gradient_* of .main-btn.
