# • Generating synthetic datasets based on ElTiempo.es forecasts, articles, images or videos
# • Persistently storing ElTiempo.es content beyond immediate retrieval use
# • Using ElTiempo.es content for dataset creation, evaluation sets or long-term learning storage
#
# Permitted:
# • Short-term, ephemeral retrieval operations (RAG) where content is not retained for training
# • On-demand access and summarization for immediate user queries
