   Dikendalikan lewat markup (lihat assets/js/case-study.js):
     data-dwell   "3000,2000,3000,2500"        ms tiap slide ditahan
     data-clicks  "0:0.931,0.057 2:0.912,0.933" slide:x,y (rasio 0-1)
   Warna bezel laptop sengaja gelap tetap, tidak ikut tema halaman —
   perangkatnya representasi fisik, bukan bagian palet situs.
