     PAGE CONTENT — Peta Laman (Sitemap)
     Site  : nres  ·  Page slug: sitemap  ·  Page ID: 41
     URL   : /nres/sitemap

     Konsep: peta laman penuh, dijana AUTOMATIK daripada menu navbar publik
             ($menuTree dari PortalHandler) — jadi ia sentiasa selari dengan
             struktur navigasi sebenar tanpa penyelenggaraan manual.

     Sumber data:
       · $menuTree  → pokok menu publik (navbar) — nama sudah diterjemah via t()
       · $sitePages → senarai halaman site (untuk seksyen "Halaman Lain")

     Item tanpa menu_link dipaparkan sebagai teks biasa (struktur sahaja).
     BM/EN ikut sesi. CSS sendiri (kelas .sm-*).
