Tutorial: settingsSync

The settingsSync project manages the synchronization of user configuration and memory files between the local environment and the remote backend. It utilizes an Incremental Upload Strategy to efficiently push only changed settings to the cloud and a Memoized Download Strategy to retrieve and cache remote configurations during startup, ensuring a consistent application state without redundant network requests.
