+/**
+ * A provider for the [MobileConnectionsRepository] interface that can choose between the Demo and
+ * Prod concrete implementations at runtime. It works by defining a base flow, [activeRepo], which
+ * switches based on the latest information from [DemoModeController], and switches every flow in
+ * the interface to point to the currently-active provider. This allows us to put the demo mode
+ * interface in its own repository, completely separate from the real version, while still using all
+ * of the prod implementations for the rest of the pipeline (interactors and onward). Looks
+ * something like this:
+ *
+ * ```
+ * RealRepository
+ *                 │
+ *                 ├──►RepositorySwitcher──►RealInteractor──►RealViewModel
+ *                 │
+ * DemoRepository
+ * ```
+ *
+ * NOTE: because the UI layer for mobile icons relies on a nested-repository structure, it is likely
+ * that we will have to drain the subscription list whenever demo mode changes. Otherwise if a real
+ * subscription list [1] is replaced with a demo subscription list [1], the view models will not see
+ * a change (due to `distinctUntilChanged`) and will not refresh their data providers to the demo
+ * implementation.
