/* main.css - Arsip Tugas Pemrograman
   Cara kustomisasi cepat:
   - Warna: ubah token di blok :root (tema terang), lalu samakan di dua blok tema gelap.
   - Font: ganti --font-display, --font-body, --font-mono (dan link Google Fonts di index.html).
   - Efek kaca: atur --glass, --edge, dan nilai blur() di .glass.
