/*
 * Teisou Account — design tokens.
 *
 * Satu sumber kebenaran untuk warna, spacing, radius, shadow, dan durasi
 * animasi dipakai pusat akun (/account/**) dan, menyusul di bagian 12,
 * halaman marketing (/, /apps, dst) supaya seluruh situs terasa satu
 * produk — bukan dua desain yang ditempel bersebelahan.
 *
 * Dark mode: default ikut `prefers-color-scheme`, bisa dioverride manual
 * lewat atribut `data-theme="light"|"dark"` di <html> (disimpan di
 * localStorage oleh account.js — lihat toggle di _preview.html). Baris
 * token di bawah ditulis dua kali: sekali netral/light di `:root`, sekali
 * lagi di `@media (prefers-color-scheme: dark)` DAN di `[data-theme="dark"]`
 * supaya override manual bekerja terlepas dari preferensi OS.
