+/**
+ * AppNav persistence test — verifies AppNav renders on ALL routes (/calendar, /lists).
+ *
+ * FIX 3: AppNav must be a persistent app-shell element outside <Routes> so it
+ * survives route transitions. Before the fix, AppNav was rendered INSIDE
+ * CalendarShell, which caused it to unmount when navigating to /lists.
+ *
+ * These tests render the full App component (same as the user experiences) and
+ * verify the "FamilySync" brand text (present in both PhoneNav and DesktopNav)
+ * is visible on both the /calendar and /lists routes.
