/**
 * Tests for the `developerMode` field added to themeSlice and the
 * `selectDeveloperMode` selector.
 *
 * The field is persisted via the `theme` redux-persist config (localStorage,
 * same as other theme preferences).  These tests validate the reducer + selector
 * in isolation without requiring the full persist machinery.
