   YorishID — base.css
   Tema bersama untuk index.html dan audiovisual.html.

   Konsep "dua langit": Langit Siang (terang, --sky-*) dan Langit Malam
   (gelap, --night-*). Komponen TIDAK menulis warna sendiri; mereka membaca
   token zona (--fg, --accent, --line, ...) yang diganti oleh kelas
   .zone-day / .zone-white / .zone-night. Satu komponen otomatis benar di
   latar terang maupun gelap.

   Daftar isi
     1  Token                     7  Tombol
     2  Reset                     8  Navbar & menu mobile
     3  Tipografi                 9  Footer
     4  Layout                    10 Hero (bagian bersama)
     5  Zona terang / gelap       11 Dekorasi (bintang, cincin, awan, horizon)
     6  Ikon & utilitas           12 Dialog, reveal, aksesibilitas, reduced-motion
     (10b CTA bersama ada setelah Hero)

   Aturan: tanpa selector ID untuk styling, tanpa !important (kecuali
   [hidden] dan reduced-motion), satu kelas = satu tanggung jawab.
