+- **Global Overview**: Real-time Leaflet-based map pinpointed exactly to the official Polymarket settlement airport coordinates.
+- **Progressive Background Loading**: Intelligently fetches multi-source data across all cities seamlessly without hitting rate limits.
+- **Rich Visualization**: Includes Chart.js-powered temperature trends, multi-model comparison bars, Gaussian probability distribution, and dynamic risk badges.
+- **Dual-Engine Co-existence**: Runs concurrently with the Telegram bot using a FastAPI backend, sharing the exact same data and caching layers.
