## Overview

This repository is a web-based stroke-risk prediction application. A user submits health and demographic fields; the FastAPI handler encodes categorical values, scales the feature row, runs a persisted classifier, and renders a risk message. The tree and sampled app.py support this runtime path, but the README is empty and the template contents were not sampled, so presentation wiring beyond the handler’s template use is not inferred.
