## Overview

A browser-based weather and travel recommendation app: users search a city, view live conditions, then request three weather-matched places in a modal. The frontend calls separate serverless handlers; one proxies OpenWeatherMap and the other sends a weather prompt to Groq. README documents responsive presentation and keyboard search, but the supplied excerpts do not show their wiring or styling details. Relationships below follow visible fetch calls and documented external integrations.

Main entry points: [`script.js`](https://github.com/charlesfransisco/weather-app-and-travel-recomendations/blob/main/script.js) (Search and modal logic), [`api/weather.js`](https://github.com/charlesfransisco/weather-app-and-travel-recomendations/blob/main/api/weather.js) (Weather proxy), [`api/recommend.js`](https://github.com/charlesfransisco/weather-app-and-travel-recomendations/blob/main/api/recommend.js) (Recommendation proxy), [`index.html`](https://github.com/charlesfransisco/weather-app-and-travel-recomendations/blob/main/index.html) (Weather page)
