/* =====================================================================
   Portofolio Hamdani — semauku.my.id

   Gaya: tenang & tegas. Palet netral dengan SATU aksen biru, tanpa
   gradien warna-warni, tanpa latar bergerak, tanpa efek kaca. Tujuannya
   bukan memukau, melainkan membuat perekrut cepat menemukan apa yang
   dibangun, sedalam apa, dan bagaimana menghubungi.

   Gelap sebagai bawaan, terang lewat [data-theme="light"].
   Dwibahasa: kedua bahasa dikirim, CSS menyembunyikan yang tidak aktif.
