/* Kinetic — kit design TOKENAI.
   Kinetic Typography: tipografi adalah objek utama, dan ia bergerak. Judul
   raksasa memakai font variabel Archivo yang melebar saat disorot
   (animasi sumbu wdth/wght), baris teks meluncur masuk dari sisi bergantian
   saat scroll, headline marquee berjalan tanpa henti dengan kata outline
   berselang-seling, dan tautan digarisbawahi oleh garis yang tumbuh.
   Kanvasnya kertas hangat dengan tinta hitam pekat — seperti lembar type
   specimen — plus aksen indigo elektrik dan jingga untuk kata yang disorot.
   Kit satu-tema: terang secara bawaan tanpa mode gelap — huruf hitam paling
   hidup di atas kertas. Kontrak: docs/kontrak-kit-design.md. Semua nilai
   design tinggal di :root. */
