+ * This schema design supports a local-only to sync-enabled workflow by managing data
+ * across two versions of each table: one for local-only use without syncing before a user registers,
+ * the other for sync-enabled use after the user registers/signs in.
+ *
+ * This is done by utilizing the viewName property to override the default view name
+ * of a table.
+ *
+ * See the README for details.

+ * `switchToSyncedSchema()` copies data from the local-only tables to the sync-enabled tables
+ * so that it ends up in the upload queue.
