## Overview

This is a small Streamlit fruit-and-breakfast app. Users see a breakfast menu, browse fruit nutrition from a remote CSV, request fruit advice from Fruityvice, and read or add fruit entries in Snowflake. The single source file contains the UI and all workflow logic. The advice helper currently uses a global value instead of its parameter and returns no result; the app then displays that result. The graph reflects visible calls and data transfers in the supplied source; no README or other implementation files were present.

Main entry points: [`streamlit_app.py`](https://github.com/hema960011/first_streamlit_app/blob/main/streamlit_app.py) (Streamlit app)
