# These variables apply to all configurations in this subfolder. These are automatically merged into the child
# `terragrunt.hcl` config via the include block.
# ---------------------------------------------------------------------------------------------------------------------
# Configure root level variables that all resources can inherit. This is especially helpful with multi-account configs
# where terraform_remote_state data sources are placed directly into the modules.
