## Overview

This is a Next.js 15 starter template, not a complete study-spot search product. Its visible visitor experience is a landing page with a search form and a shared site layout; the sampled search form has no submission or results flow. The app also includes a dashboard route, a hello API route, reusable UI, theme and query providers, and shared utilities. The layout’s provider and site-component wiring is visible; other routes and several capabilities are represented only by the tree or README, so their runtime connections are not inferred.

Main entry points: [`src/app/layout.tsx`](https://github.com/duyenlan151/study-travel-locations/blob/main/src/app/layout.tsx) (Root layout), [`src/app/page.tsx`](https://github.com/duyenlan151/study-travel-locations/blob/main/src/app/page.tsx) (Landing page), [`src/components/Home`](https://github.com/duyenlan151/study-travel-locations/tree/main/src/components/Home) (Landing sections), [`src/components/Footer/Footer.tsx`](https://github.com/duyenlan151/study-travel-locations/blob/main/src/components/Footer/Footer.tsx) (Footer)
