+// Single source of truth for the left navigation on EVERY page.
+//
+// Two problems this file solves:
+//
+//  1. Pages that never call renderSidebar() — it self-initialises on
+//     DOMContentLoaded, so just including the script is enough.
+//
+//  2. Pages with their own custom script that renders a DIFFERENT (shorter)
+//     menu — a MutationObserver watches the container and re-asserts the full
+//     list whenever something replaces it. This is why CDS Alerts and
+//     Observations were showing only 10 items while the Dashboard showed all
+//     of them: those pages build their own nav after this script has run.
+//
+// Adding a nav item? Add it to SIDEBAR_ITEMS and it appears everywhere.
