BlueMapS3Storage

A storage addon for BlueMap that stores map data in S3-compatible storage services (Amazon S3, Cloudflare R2, MinIO, DigitalOcean Spaces, Backblaze B2, or anything else that speaks the S3 API), instead of the local filesystem.

Useful for distributed server architectures, environments without persistent local storage, and multi-server networks that need to share the same map data.
