## Overview

TripInn-Ticket- is a browser-based digital travel-pass preview and sharing app. A user supplies a pass link, or uses the documented preview mode; the controller handles pass data and requests ticket rendering, then supports PNG download and sharing. The sampled code also shows a QR-code service integration. The tree does not contain the README’s referenced ticket.html, and the excerpts do not show all page wiring, so the graph focuses on evidenced runtime behavior.

Main entry points: [`ticket.js`](https://github.com/gunal-k/tripinn-ticket/blob/main/ticket.js) (Pass and UI controller)
