+3. **Operational Efficiency**: Task management, batch tracking, and automated schedules (IPM, feeding).
+4. **Data-Driven Insights**: Real-time environmental metrics and historical reporting.
+
+## Key Features
+
+- **3D Facility Viewer**: Interactive "Time Machine" to view plant states at any point in history.
