Notes
- All temperature sensors use hysteresis to prevent alert bouncing (±1°C deadband)
- Voltage thresholds are absolute values without hysteresis
- Boolean alerts (errors/faults) are either active (true) or inactive (false)
- Critical alerts trigger red screen border and vibration
- Warning alerts are displayed in yellow
