-.PersistentVolumeClaim (PVC) path logic

-PVCs mount as a directory. The mount path is determined by the first available value in the following order:
-
-.  `spec.application.extraFiles.pvcs[].mountPath` (Specific path for the PVC).
-.  `spec.application.extraFiles.mountPath` (Default path for all extra files).
-.  The {backstage} container `WorkingDir`.
-.  The default Kubernetes path: `/opt/app-root/src`.

 = Injecting extra files and environment variables into {backstage} containers
 
-You must use the `spec.application` path to configure the injection of extra files and environment variables into your {backstage} Pod containers. This ensures necessary configurations, credentials, and dependencies (such as certificates) are available at runtime.
-
 By default, files mount only to the `backstage-backend` container. If the `containers` field is not specified, the volume mounts to the `backstage-backend` container only. You can also specify other targets, including a list of containers by name (such as `dynamic-plugin-install` or custom sidecars) or opt to in all containers in the {backstage} Pod.
 
-. To mount files, PVCs, and injecting environment variables into different container targets., apply the configuration to your `{product-custom-resource-type} custom resource (CR)` as shown in the following code:
