## Overview

WeatherApp is an Angular weather dashboard: users search for a city or use their location, then view current conditions and a forecast. The root component coordinates the selected city; weather components request their respective data through a shared service, which calls OpenWeather. Geolocation uses the browser API to obtain coordinates and resolves them to a city through that service. The component templates are listed but were not sampled, so template-level bindings are inferred only where component interfaces support them.

Main entry points: [`src/app/services/weather.service.ts`](https://github.com/dreezytrial/weather-app/blob/main/src/app/services/weather.service.ts) (Weather API client), [`src/app/app.ts`](https://github.com/dreezytrial/weather-app/blob/main/src/app/app.ts) (App coordinator), [`src/app/services/geolocation.ts`](https://github.com/dreezytrial/weather-app/blob/main/src/app/services/geolocation.ts) (Geolocation resolver), [`src/app/components/search/search.component.ts`](https://github.com/dreezytrial/weather-app/blob/main/src/app/components/search/search.component.ts) (City search)
