/* ============================================================================
   SHADOWS OVER WESTGATE — top bar controller
   ----------------------------------------------------------------------------
   Paste into ACP -> Settings -> Custom Content -> "Custom JavaScript".
   (In the live theme this can instead live in the theme's client-side bundle.)

   WHY THIS FILE EXISTS
   - The two static pages (home.html / join-the-team.html) need NO JavaScript;
     they are pure HTML/CSS (the only inline bit is an <img onerror> fallback).
   - The TOP BAR needs this small controller for: Forums mega-menu, inline
     search, the mobile burger/drawer, and the drawer's Forums accordion.

   NODEBB-SPECIFIC NOTES
   - NodeBB is a single-page app: it swaps #content on navigation instead of
     reloading. So we DON'T bind to specific nodes on DOMContentLoaded — we use
     event delegation on `document`, which keeps working across page changes and
     even if the header is re-rendered.
   - Inline <script> inside an HTML widget is sanitised/unreliable, which is the
     other reason the logic lives here rather than in the pasted markup.
   - The live notification / chat / user dropdowns come from Harmony and carry
     their OWN JavaScript. If you keep those, you do NOT need this script to open
     them — only the Forums menu, search, and mobile drawer below.
   - The preview-only member/guest switch from top-bar.html is intentionally
     omitted; in production the cluster is chosen server-side ({{{ if loggedIn }}}).
