## Overview

This is a public website for an accounting and financial consulting firm, with client account access and an administrator area. The main client journey is to browse services, use the on-page calculator or document checklist, and submit a contact request; administrators can review messages and registered users. The graph includes the sampled PHP account/data layers and documented browser interactions. The README is empty, and several endpoint implementations are unsampled, so their internal wiring is not inferred.

Main entry points: [`classes/controler.class.php`](https://github.com/adonias-sol/accounting_firm/blob/main/classes/controler.class.php) (Controller), [`classes/View.class.php`](https://github.com/adonias-sol/accounting_firm/blob/main/classes/View.class.php) (Login logic), [`classes/Model.class.php`](https://github.com/adonias-sol/accounting_firm/blob/main/classes/Model.class.php) (Data model), [`services.html`](https://github.com/adonias-sol/accounting_firm/blob/main/services.html) (Services)
