DataPrism Cloud Storage Demo

Demonstration of CORS-aware cloud storage integration with automatic proxy fallback using real NYC taxi trip data (50MB Parquet file from CloudFlare R2 with proper CORS configuration).

Engine Loading: This demo loads the DataPrism engine from CDN (https://srnarasim.github.io/dataprism-core/dataprism-core.min.js) as a UMD bundle via script tag, with automatic fallback to mock implementation for resilience. Check browser console for loading details.
