# The rest of the infrastructure is defined in modular files:
# - vpc.tf            → Networking layer (VPC, subnets, routing)
# - cluster.tf        → ECS Cluster creation
# - task_definitions.tf → App containers definitions
# - service.tf        → ECS Services and scaling
# - roles.tf          → IAM roles for ECS/Fargate tasks
# - security.tf       → Security Groups and policies
# - outputs.tf        → Exports key resources for integration

# Keep this file light and descriptive.
# Your main.tf is the entry point to a production-grade IaC stack.
