/* ============================================================================
   "What's new" — left-nav footer trigger + release-notes modal.

   Paired with app/Views/layout/_whats_new_modal.php, the footer trigger in
   app/Views/layout/app.php, and public/assets/js/whats-new.js. Fully tokenised
   (:root vars → automatic dark mode); the base .modal__dialog already has a
   dark override (style.css), so only our custom surfaces need explicit dark
   rules below. The dialog chrome + full-screen mobile come from `.modal--sheet`.
