## Overview

This is a Flask-based cloud monitoring dashboard. Operators and customer-facing users interact with the web app for dashboards and login-related events; the app exposes monitoring and alert behavior backed by Google Cloud services. The sampled source shows asynchronous log delivery, metric reads, and Firestore-backed alert acknowledgements. The README provides no capability detail, and the source excerpts are partial, so other product features and some route wiring are not represented.
