+The user explicitly requested a permanent OLED-black theme, charcoal glass-like cards,
+muted gold and cyan accents. These app resources intentionally override the shared
+DESIGN.md palette, DayNight preference and flat-surface rules. Do not overwrite them
+with the shared token generator. Use static gradients rather than continuous effects;
+keep large touch targets, readable text and null telemetry shown as a dash.
+Wide layouts start at 1000dp; narrower windows use a bottom navigation bar.

-1. **Telemetry is read-only.** The explicitly requested SWI69 WinClose integration is
-   the only vehicle-write exception: an opt-in service closes the four windows on the
-   WinClose door callback, requiring P and readable 0 km/h before and during the pulse.
-   It uses WinClose's CarState/VSM interfaces and the shared VehicleWriteGate; no other

 2. **A failed read is not a zero.** Getters return `Integer`/`Float`/`Boolean` and `null`
    means "could not read". Null fields are omitted from the payload. Sending 0 for SOC
    tells ABRP the battery is empty and wrecks a live route plan.
