# Libre DevOps Terraform module task runner. Run `just` to list recipes.
#
# Install just with either:
#   brew install just
#   uv tool add rust-just     # then call recipes as: uv run just <recipe>
#
# The recipes wrap the LibreDevOpsHelpers engine functions in PowerShell so local development
# mirrors the libre-devops/terraform-azure action. plan/apply/destroy use the remote azurerm
# backend and perform the same storage firewall "open before, close after" dance the action does,
# reading the state coordinates from the TFSTATE_* environment variables published by the tenant
# bootstrap:
#   export TFSTATE_RESOURCE_GROUP=...  TFSTATE_STORAGE_ACCOUNT=...  TFSTATE_BLOB_CONTAINER=...
# Authenticate first with `az login`. The workspace selects the environment (default dev, or set
# TF_WORKSPACE).
