Okay, let's start building a basic structure for the Logistics Automation Tool using HTML, CSS, and JavaScript. This initial version will focus on setting up the layout and placeholders for the features. We'll use the Leaflet library for mapping. Logistics Automation Tool

Initialize a Leaflet map. 2. Define and display mock shipment data with markers on the map. 3. Define and display mock inventory data. 4. Provide basic functionality to add/update inventory items via input fields. 5. Implement a simple alert system logging messages to a dedicated section. 6. Include a basic simulation loop (`setInterval`) to randomly move "In Transit" shipments and update their display. 7. Perform basic low-stock checks and display alerts. 8. Include placeholder functions and sections for Route Optimization and Predictive Analytics. You can view this by opening the `index.html` file. The map will show initial shipment locations, the inventory will be listed, and alerts (like initial low stock) will appear. Shipments marked "In Transit" will slowly move randomly on the map every 5 seconds.
