## Overview

FGT PRO is a browser-based investment-management application with member and administrator interfaces. Members register or log in, manage investment plans and balances, and access affiliate, market-signal, and points-reward features; administrators manage users, transactions, plans, settings, and redemptions. The sampled code identifies localStorage as the persistence layer. Source excerpts are partial, and the README is empty, so interface-to-feature wiring not demonstrated in the excerpts is omitted.

Main entry points: [`js/db.js`](https://github.com/ijoben/invest/blob/main/js/db.js) (State service), [`js/admin-page.js`](https://github.com/ijoben/invest/blob/main/js/admin-page.js) (Admin controller), [`js/app.js`](https://github.com/ijoben/invest/blob/main/js/app.js) (App controller), [`js/admin.js`](https://github.com/ijoben/invest/blob/main/js/admin.js) (Admin controls)
