 A variable group allows you to define and store related environment variables that can be imported together in a codemagic.yaml file. For instance, you might create separate `staging` and `production` groups, each containing variables with the same names but different values. By importing the appropriate group in your workflow, you can reuse the same script logic while dynamically applying environment-specific configurations.
