/* ============================================================
   SAISER - инженерные системы зданий, Алматы.
   Сигнатура: «инженерные слои здания» - разрез здания, по которому от кросса
   тянутся трассы систем и загораются устройства. Фото-плиты раскрываются
   гребёнкой: стояк слева растёт вверх, от него по этажам вправо уходят полосы.
   Плиты: .pw (обёртка) > .plate (sticky); прогресс в --enter/--exit/--stay/--open.
   Шрифты: Ubuntu Condensed (дисплей) + Inter Tight (текст) - оба с казахскими глифами.
