   LATAR BERGERAK
   =========================================================
   Empat lapis yang bergerak dengan kecepatan berbeda, semuanya
   murni CSS (tanpa canvas tambahan, tanpa file gambar):

     1. Nebula   — dua gumpalan warna yang mengapung pelan
     2. Kabut    — sapuan halus melintas horizon
     3. Cahaya   — sorot lembut yang bernapas dari atas
     4. Bintang jatuh — sesekali melintas

   Semua pakai transform/opacity saja, jadi dikerjakan GPU
   dan tidak membebani HP.
