 ---
 
-### Scenario 1: New VNet + Hub Peering
-Ideal for isolated workloads that need connectivity to hub network and on-premises resources.
-
-```hcl
-provider "azurerm" {
-  alias           = "hub"
-  subscription_id = "hub-subscription-id"
-}
-
-module "acr" {
-  source = "./buildingblock"
-
-  providers = {
-    azurerm     = azurerm
-    azurerm.hub = azurerm.hub
-  }
-
-  acr_name                      = "mycompanyacr"
-  resource_group_name           = "acr-rg"
-  location                      = "West Europe"
-  sku                           = "Premium"
-  admin_enabled                 = false
-  public_network_access_enabled = false
-
-  # Private endpoint - creates new VNet
-  private_endpoint_enabled = true
-  private_dns_zone_id      = "System"
-  vnet_address_space       = "10.250.0.0/16"
-  subnet_address_prefix    = "10.250.1.0/24"
-
-  # Hub connectivity - peering created automatically
-  hub_subscription_id     = "hub-subscription-id"
-  hub_resource_group_name = "hub-network-rg"
-  hub_vnet_name           = "hub-vnet"
-
-  retention_days       = 30
-  trust_policy_enabled = true
-
-  tags = {
-    Environment = "Production"
-  }
-}
-```
-
-### Scenario 2: Existing Shared Connectivity VNet
-Ideal for multi-tenant environments with a shared connectivity VNet already peered to hub.
-
-```hcl
-module "acr" {
-  source = "./buildingblock"
-
-  acr_name                      = "mycompanyacr"
-  resource_group_name           = "acr-rg"
-  location                      = "West Europe"
-  sku                           = "Premium"
-  admin_enabled                 = false
-  public_network_access_enabled = false
-
-  # Private endpoint in existing shared VNet
-  private_endpoint_enabled          = true
-  private_dns_zone_id               = "System"
-  vnet_name                         = "shared-connectivity-vnet"
-  existing_vnet_resource_group_name = "connectivity-rg"
-  subnet_name                       = "acr-subnet"
-
-  # No hub peering - VNet already connected to hub
-  # hub variables omitted
-
-  tags = {
-    Environment = "Production"
-  }
-}
-```
-
-### Scenario 3: Private Isolated (No Hub)
-Ideal for secure workloads that only need access within the same VNet (e.g., AKS in same VNet).
-
-```hcl
-module "acr" {
-  source = "./buildingblock"
-
-  acr_name                      = "mycompanyacr"
-  resource_group_name           = "acr-rg"
-  location                      = "West Europe"
-  sku                           = "Premium"
-  admin_enabled                 = false
-  public_network_access_enabled = false
-
-  # Private endpoint - new isolated VNet
-  private_endpoint_enabled = true
-  private_dns_zone_id      = "System"
-  vnet_address_space       = "10.250.0.0/16"
-  subnet_address_prefix    = "10.250.1.0/24"
-
-  # No hub connectivity
-  # hub variables omitted
-
-  tags = {
-    Environment = "Production"
-  }
-}
-```
-
-### Scenario 4: Completely Public ACR
-Ideal for development/test environments or public CI/CD pipelines.
-
-```hcl
-module "acr" {
-  source = "./buildingblock"
-
-  acr_name            = "mycompanyacr"
-  resource_group_name = "acr-rg"
-  location            = "West Europe"
-  sku                 = "Standard"  # Can use cheaper SKU
-  admin_enabled       = false
-  public_network_access_enabled = true
-
-  # No private endpoint
-  private_endpoint_enabled = false
-
-  # Optional: IP allowlist for security
-  allowed_ip_ranges = [
-    "203.0.113.0/24",  # Office network
-    "198.51.100.5/32"  # CI/CD runner
-  ]
-
-  tags = {
-    Environment = "Development"
-  }
-}
-```

-### Private ACR with AKS Integration
-```hcl

-
-  # Automatic AKS integration - grants AcrPull role
-  aks_managed_identity_principal_id = module.aks.aks_identity_client_id
-
-  tags = {
-    Environment = "Production"
-  }
-}

-### Geo-Replicated ACR (Premium)
-```hcl
-module "acr" {
-  source = "./buildingblock"
-
-  acr_name            = "mycompanyacr"
-  resource_group_name = "acr-rg"
-  location            = "West Europe"
-  sku                 = "Premium"
-
-  # Geo-replication to multiple regions
-  georeplications = [
-    {
-      location                  = "North Europe"
-      zone_redundancy_enabled   = true
-      regional_endpoint_enabled = true
-    },
