   BACKGROUND PER HALAMAN — satu lapisan tetap (ringan)
   Dulu tiap halaman memakai "background-attachment: fixed" dengan foto
   besar: browser harus menggambar ulang foto itu di SETIAP gerakan scroll
   (penyebab utama lag di HP). Sekarang foto ada di satu lapisan fixed
   (html::before) yang diganti lewat atribut html[data-bg] (diatur
   showPage() di script.js), jadi digambar sekali saja.
   - Foto hanya dimuat di layar lebar & bukan mode hemat (HP cukup gradasi,
     karena fotonya hanya terlihat samar di balik lapisan putih).
   - PENTING: link LinkedIn di bawah memakai token (?e=1790812800) yang
     KEDALUWARSA pada 1 Oktober 2026. Unduh gambarnya, taruh di folder
     project (mis. img/bg-beranda.jpg), lalu ganti url() di variabel ini.
