# Setup: HuggingFace-optimized data loading
# ============================================================================
# This version uses GDAL virtual file system and temporary downloads
# for efficient loading in cloud/ephemeral environments like HuggingFace Spaces.
# For local development with persistent caching, use setup_local.R instead.
