## Overview

This is an Express API for institute accounts, course management, question banks, and payment-backed passkey issuance. The principal flow is an institute authenticating, managing courses, creating or retrieving question sets, then checking out and saving paid passkeys. Routes and controller-to-model/provider links below are grounded in sampled files; the tree also shows student-auth, nano-ID, and order-completion modules, but their wiring and behavior were not sampled, so they are not expanded.

Main entry points: [`server/index.js`](https://github.com/ilix-studio/content-specific-system/blob/master/server/index.js) (Express app), [`server/controllers/newPaymentController.js`](https://github.com/ilix-studio/content-specific-system/blob/master/server/controllers/newPaymentController.js) (Checkout and passkeys), [`server/routes/authR/instituteAuthRoutes.js`](https://github.com/ilix-studio/content-specific-system/blob/master/server/routes/authR/instituteAuthRoutes.js) (Institute routes), [`server/controllers/aboutCourseController/courseControllers.js`](https://github.com/ilix-studio/content-specific-system/blob/master/server/controllers/aboutCourseController/courseControllers.js) (Course management)
