## Overview

The repository contains two React products. Monsters Rolodex fetches user records, filters them by a search term, and displays matching cards. Crwn Clothing is an e-commerce storefront with home, shop, authentication, and checkout routes; its documented capabilities include Firebase-backed accounts and Google sign-in. The graph shows only call and data-flow relationships supported by sampled source or the README. Several storefront component connections and Firebase internals are not sampled, so those links are left out.
