## Overview

This Flask application records student attendance, serves attendance records, and provides date-range analytics with an optional student filter. The main workflow is a user submitting student registration or absence through the web interface; routes invoke model operations, which persist or query MySQL. The app initializes its database at startup. Source confirms these runtime relationships; deployment details in the README are omitted because they are not part of the application runtime.

Main entry points: [`app/routes.py`](https://github.com/fahimahammed/docknflow/blob/main/app/routes.py) (Request routes), [`app/database.py`](https://github.com/fahimahammed/docknflow/blob/main/app/database.py) (Database setup), [`app/static/styles.css`](https://github.com/fahimahammed/docknflow/blob/main/app/static/styles.css) (Page styles), [`app/__init__.py`](https://github.com/fahimahammed/docknflow/blob/main/app/__init__.py) (Flask initialization)
