/* ENTRY LAB — «прилад».
   Авторське: графітова основа, тепле біле, один сигнальний колір, точкова матриця 5×7 як єдиний
   дисплейний голос, композиція «рейка / бриф / інструменти» і стан, що читається формою.
   Від Apple — матеріали й типографіка: нейтральний гротеск з оптичним розміром, звичайний регістр,
   заливки замість рамок, заокруглення за шкалою, розмиття лише там, де під елементом щось є.
   Моноширинний шрифт — тільки для коду, термінала, даних і кодів доступу. */
