This replaces the earlier Pico dashboard concept as the active dashboard architecture.
The Dashboard ESP32-S3 communicates with the Cargo ESP32 over WiFi/HTTP REST for v1. CAN/OBD-II support remains a future dashboard-side vehicle-visualization feature and is not part of the Cargo ESP32 role.
## Existing DS18B20 Temperature Support
DS18B20 temperature sensor support is already part of the Cargo ESP architecture.
Current responsibility split:
- Cargo ESP32 owns DS18B20 sensor reading.
- Cargo ESP32 exposes temperature state through the WebUI/API path.
- Dashboard ESP32-S3 should consume temperature data from the Cargo ESP API.
- Dashboard ESP32-S3 should not wire directly to cargo-area DS18B20 sensors for v1.
This means future dashboard work should display existing Cargo ESP temperature telemetry rather than reimplementing temperature sensing on the dashboard.
