What is the recommended path to override /libs standard functionality?

The recommended path to override /libs standard functionality is /apps. The /apps folder contains application-specific code and configuration that can extend or override the default functionality provided by /libs. The /apps folder has precedence over the /libs folder, meaning that if there are two resources with the same path under both folders, the one under /apps will be used.
