# This pipeline works across multiple terragrunt projects within a team
# directory with locking (turnstyle) and PR comment functionality.
#
# The init step figures out which projects to plan/apply
# The plan/apply steps run across each project as a matrix
#
# It allow both plan/apply via manual dispatch.
# For CI/CD, it runs a plan when PR raised and apply when merged.
