## Overview

This is a small Expo weather-dashboard app scaffold. The visible workflow is to browse placeholder city weather, open a city detail screen, and save or clear favorite cities; settings currently hold only local toggle state. Weather lookup and persistence are not implemented in the sampled code. The map reflects the supplied excerpts and source index; some screens and layouts are listed but their internal behavior was not shown.

Main entry points: [`src/app/_layout.jsx`](https://github.com/ezekiel-serva/global-weather-dashboard/blob/main/src/app/_layout.jsx) (Root layout), [`src/app/(tabs)/dashboard.jsx`](https://github.com/ezekiel-serva/global-weather-dashboard/blob/main/src/app/(tabs)/dashboard.jsx) (Dashboard), [`src/app/(tabs)/favorites.jsx`](https://github.com/ezekiel-serva/global-weather-dashboard/blob/main/src/app/(tabs)/favorites.jsx) (Favorites screen), [`src/components/CityCard.jsx`](https://github.com/ezekiel-serva/global-weather-dashboard/blob/main/src/components/CityCard.jsx) (City card)
