# -- REQUEST TAG ENFORCEMENT --
# SGs use IDs in ARNs so DenyBadName can't enforce naming.
# Require team tag on create — Terraform default_tags handles this.
# Only the SG resource: CreateSecurityGroup is also authorized against
# the VPC, where request tags are never present, so "*" denied it always.
