# minio-switch.sh — swap MinIO target between local container and CAI cluster
#
# Usage:
#   ./minio-switch.sh cluster         # → cluster <minio-host> (didi-prod bucket)
#   ./minio-switch.sh local           # → staging-dataLayer-minio (multi-bucket)
#   ./minio-switch.sh status          # show current
#
# Like redis-switch.sh, this rewrites the MINIO_* block in agent-v3 + framework
# .env files and restarts both stacks. Cluster credentials live in
# .cluster-credentials.env (gitignored) — same file used by redis-switch.sh.
