## Overview

Unique Twelve is a single-file finance dashboard for a 12-member savings group. Members and administrators use the dashboard to review and manage contributions, accounts, expenses, assets, reports, and group documents; administrators also handle payments, imports, identity cards, and maintenance actions. The documented deployment offers Firebase or a Google Sheets/Apps Script alternative, with browser-local demo storage and optional GitHub backups. Feature modules all point to index.html because the README describes the dashboard as one file; no source excerpts were provided, so internal call relationships are not inferred.

Main entry points: [`index.html`](https://github.com/mamunbracu/unique-12/blob/main/index.html) (Finance dashboard), [`Code.gs`](https://github.com/mamunbracu/unique-12/blob/main/Code.gs) (Apps Script backend), [`firestore.rules`](https://github.com/mamunbracu/unique-12/blob/main/firestore.rules) (Firestore rules)
