   gis-map/frontend/css/olt.css  — v2.9
   Restyle halaman OLT/GPON: sidebar kartu, header detail, ringkasan
   global, filter PON, dan tabel ONU.

   REVISI Sep 2026 (bug "scroll tabel ONU macet-macet", laporan Indra):
   bagian "Tabel ONU" di bawah dapat aturan tambahan khusus performa scroll.
   Penjelasan tiap aturan ada tepat di atasnya. Selain itu murni visual —
   semua id & onclick handler yang dipakai olt.js TIDAK diubah.

/* ═══ Tabel ONU ═══════════════════════════════════════════
   Tiga aturan pertama di bawah khusus PERFORMA SCROLL (bug "macet-macet"):

   1. `contain: layout paint style` pada kontainer scroll = janji ke browser
      bahwa perubahan isi di dalam div ini TIDAK memengaruhi layout apa pun
      di luarnya. Jadi saat olt.js mem-patch sel (traffic/uptime berubah tiap
      3 detik), browser cukup menghitung ulang bagian dalam tabel, bukan
      seluruh halaman (sidebar, header sticky, panel info di bawah).

   2. `overflow-anchor: none` mematikan "scroll anchoring" Chrome. Fitur itu
      diam-diam menggeser scrollTop supaya elemen yang sedang dilihat tetap
      di tempat ketika tinggi konten berubah -- pada tabel yang isinya
      di-update terus, justru itulah yang terasa sebagai loncatan/nyendat.

   3. `-webkit-overflow-scrolling: touch` + `scrollbar-gutter: stable`
      bikin scroll lebih halus di trackpad/touch dan mencegah lebar konten
      bergeser tiap scrollbar muncul-hilang.
