   HALAMAN PUSAT BANTUAN — /bantuan/
   ═══════════════════════════════════════════════════════════════════════════
   Berkas terpisah supaya utama.css tidak membengkak untuk halaman lain.
   Warnanya menumpang token yang sudah ada di utama.css, jadi satu keluarga
   dengan halaman lain tanpa mengulang definisi.

   Perombakan dari halaman lama:
     - tab (5 kotak yang isinya tersembunyi) DIBUANG, diganti satu halaman
       mengalir + menu bagian yang menempel
     - semua yang bisa diklik minimal 48px di HP
     - kontak dinaikkan ke atas
     - tidak ada Bootstrap, tidak ada jQuery, tidak ada Font Awesome

/* PENTING — kenapa baris ini ada.
   utama.css memasang "overflow-x: hidden" di html dan body untuk mencegah
   gulir mendatar. Efek sampingnya: body jadi WADAH GULIR, dan itu mematikan
   position:sticky — menu bagian di bawah ikut tergulir hilang (terbukti saat
   diuji: posisinya -3542px, jauh di luar layar).

   "clip" menahan gulir mendatar persis seperti "hidden", TAPI tidak membuat
   wadah gulir, jadi sticky tetap hidup. Berkas ini hanya dimuat di
