+<!-- Scroll the active sidebar link into view after page load.
+     Starlight's SidebarPersister restores scrollTop from sessionStorage,
+     but when navigating via crosslink to a different section, the restored
+     position is stale and the active link ends up off-screen. This script
+     runs after Starlight's inline restoration (which fires synchronously
+     before DOMContentLoaded) and uses `block: 'center'` to place the
+     active link in the middle of the sidebar viewport for orientation.
+     Desktop only -- on mobile the sidebar is a drawer that scrolls
+     independently. -->
