/* Ekran logowania w planerze i planie lekcji: ten sam wygląd co na stronie głównej.
   Wzór to sekcja „LOGOWANIE” w style.css i reguły niskiego ekranu w js/core/pasek-telefonu.css, których te strony nie wczytują.
   Podgląd NH-logowanie-wyglad porównuje trzy ekrany, więc zmiana wzoru wymaga tej samej zmiany tutaj.
   Reguły zaczynają się od #login-screen, żeby nie zależały od ogólnych stylów planera i planu lekcji. */
