/* Sim 05 in the dress of 1901–1903: the shared HUD's layout, but every panel
   is aged paper or card, lettered in ink with a Victorian serif (Old Standard)
   and typewriter figures (Special Elite); sliders are brass on wood, buttons
   are stamped card, the readouts are dial gauges, and the 3D labels are
   paper shipping tags on a string. Only this sim is restyled. */
