# Unified cleanup script for the consolidated Function App + Azure Front Door samples.
#
# This script deletes the resource group created by scripts/deploy_all.sh. It can read
# the resource group from an env file produced by the deploy script or accept it via flag.
#
# Usage examples:
#   # Using the env file written by deploy_all.sh
#   bash ./scripts/cleanup_all.sh --env-file ./scripts/.last_deploy_all.env --use-localstack
#
#   # Passing the RG directly (works for Azure or LocalStack)
#   bash ./scripts/cleanup_all.sh --resource-group rg-funcafdall-12345
#
# Requirements: az CLI
# Optional: azlocal (LocalStack Azure CLI helper) when cleaning emulator resources
