Notes

• Always run terraform plan before apply to review changes.
• Use -no-color flag for clean output in non-terminal environments.
• Never run terraform destroy without explicit user confirmation.
• Use workspaces or separate state files for environment isolation.
• Backend configuration (S3, Azure Blob, GCS) should be set in terraform config, not CLI.
