Update Route53 DNS record to use IP in new CIDR range.
The vpc_cidr override in dev/vpc/terragrunt.hcl is correctly set to 10.1.0.0/16. However, dev/route53/terragrunt.hcl (line 41) contains a hardcoded DNS A record with IP 10.0.0.100, which falls in the old CIDR range (10.0.0.0/16) and will be invalid after this VPC change.
Update the custom DNS record for "api.dev.example.com" to use an IP address within the new 10.1.0.0/16 range, or remove it if no longer needed.
Additionally, note that VPC CIDR changes require recreating the VPC and associated resources. Verify that any other applications or configurations with hardcoded IPs in the 10.0.0.0/16 range are updated accordingly.

In dev/route53/terragrunt.hcl around line 41, the DNS A record for
"api.dev.example.com" is hardcoded to 10.0.0.100 (old 10.0.0.0/16 CIDR); update
that A record to an IP within the new VPC CIDR 10.1.0.0/16 (e.g., 10.1.x.y) or
remove the custom record if it's no longer needed, and then search the repo for
any other hardcoded 10.0.0.0/16 addresses to update accordingly; remember that
changing the VPC CIDR requires recreating the VPC and dependent resources, so
plan for resource replacement and validate references after updating the record.
