/* learn — konsola do mowienia.
 *
 * Pomysl: czarna plyta czolowa z jednym zrodlem swiatla. Swieci wylacznie przycisk
 * nadawania; zdanie do wypowiedzenia jest wysrodkowane i skladane szeryfem, bo to
 * material jezykowy, a nie element interfejsu. Cala reszta chromu jest wyciszona.
 * Kolor swiatla niesie informacje: zielen = angielski, bursztyn = hiszpanski.
 *
 * Czern, wysrodkowanie i zielen odpowiedzi sa przejete ze starszej strony uzytkownika
 * (~/old_www/angielski), ktorej uklad sprawdzil sie w praktyce.
