## Overview

This Flask application serves introductory/about pages, supports account registration and login, and provides user listing, lookup, and editing through HTML pages and JSON endpoints. A separate spam generator creates simulated fall and impact sensor readings and posts them to the app, where they are stored and can be listed. The graph follows sampled route/service/repository calls; sensor and spam-generator connections are documented in their source. Some template and model details were not sampled, so uncertain rendering and persistence links are omitted.

Main entry points: [`src/app.py`](https://github.com/oleksandrlinenko/flask/blob/main/src/app.py) (Flask app), [`src/routes/spaming.py`](https://github.com/oleksandrlinenko/flask/blob/main/src/routes/spaming.py) (Spam routes), [`src/routes/users.py`](https://github.com/oleksandrlinenko/flask/blob/main/src/routes/users.py) (User routes), [`src/services/user_service.py`](https://github.com/oleksandrlinenko/flask/blob/main/src/services/user_service.py) (User service)
