## Overview

This is a browser-based veterinary clinic system with pet-owner and clinic-staff workflows. Pet owners can manage pets, book appointments and review health records; clinic users also have clinic and user administration, queue, treatment, and billing screens. The Express server handles the application APIs and MySQL access, while separate schema initializers prepare clinical and billing tables. The README provides no product description, and several page scripts and server sections were not sampled, so their specific API wiring is left unverified.

Main entry points: [`server.js`](https://github.com/chykrsr/devtools_project/blob/main/server.js) (Clinic application API), [`routes/billing.js`](https://github.com/chykrsr/devtools_project/blob/main/routes/billing.js) (Billing API), [`lib/clinical-schema.js`](https://github.com/chykrsr/devtools_project/blob/main/lib/clinical-schema.js) (Clinical schema setup), [`lib/billing-schema.js`](https://github.com/chykrsr/devtools_project/blob/main/lib/billing-schema.js) (Billing schema setup)
