# This project supports S3-compatible object storage such as:

# - Cloudflare R2
#
# IMPORTANT:
# - On Railway, these variables are injected automatically
#   when you connect a Storage Bucket to the service.
# - You do NOT need to set them manually on Railway.
#
# Uncomment and configure ONLY if you are using S3 outside Railway.
