## Overview

This is a small appointment-booking web app: a visitor opens the appointment form, submits booking details, and the server emails them to the configured Gmail account. The sampled code shows the browser interaction, POST request, server handler, and email dispatch. The HTML and CSS are present in the tree but were not excerpted, so their wiring and presentation details are not inferred.

Main entry points: [`script.js`](https://github.com/gokulskr/car-care-realtime-node/blob/main/script.js) (Form interaction), [`server.js`](https://github.com/gokulskr/car-care-realtime-node/blob/main/server.js) (Booking handler)
