/*
 * Bubble Runes — sito
 *
 * Le palette sono quelle vere dei temi del gioco: nell'app ricolorano i menu, e qui fanno la stessa
 * cosa con la pagina. Non è un vezzo — gli otto temi sono il contenuto principale della 3.0, e
 * farli vedere addosso al sito li dimostra invece di descriverli.
 *
 * Se in futuro si aggiunge una skin al gioco: una regola [data-theme="<id>"] qui sotto, una voce
 * nel selettore di theme.js, l'emblema in assets/img/emblems/<id>.webp. Nient'altro.
