   Dark is the dashboard at dusk. Light is the same instrument seen in daylight:
   paper-pale surfaces, cool steel structure — but the odometer window stays dark
   in both. A real car keeps a dark instrument panel at noon, so it reads as
   intentional, and it keeps the one element you squint at while driving at full
   contrast regardless of theme. */
