// 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.
