/* Cyberpunk — kit design TOKENAI.
   High-tech dystopian: latar malam biru-hitam ber-grid dengan cahaya kota neon,
   aksen cyan/magenta/kuning menyala, tombol chamfer (sudut terpangkas) ala HUD,
   headline glitch beraberasi kromatik, garis holografik, ikon heksagon, scanline
   CRT tipis, dan tipografi Orbitron/Rajdhani. Kit satu-tema: gelap secara bawaan,
   tanpa mode terang — dystopia tidak mengenal siang.
   Kontrak: docs/kontrak-kit-design.md. Semua nilai design tinggal di :root. */
