/**
 * Dua tema tersedia: "terang" (bawaan) dan "redup".
 *
 * Redup bukan mode gelap — susunan terang-gelapnya tetap sama (latar lebih tua
 * daripada kartu), hanya seluruh permukaan diturunkan kecerahannya dan diberi
 * rona hangat supaya nyaman dipakai lama. Karena semua warna di berkas ini
 * mengambil dari token di bawah, mengganti tema cukup menimpa blok token ini.
