/* Sim 06 dressed for the sea: the shared HUD's layout, with panels like
   brass-bound navy plaques, an engraved serif (Cinzel) for headings, an
   old-style book face (Crimson Pro) for text and a typewriter (Courier
   Prime) for the numbers; brass sliders and dials, signal-flag accents.
   Only this sim is restyled. */
