## Overview

#### Purpose and Entry Point

This is a Python Streamlit application. The primary executable entry point is `app.py`, intended to run under the Streamlit runtime and present an interactive UI. No README-defined domain behavior is available.

#### Application UI Layer

`app.py` is the central application composition point: it likely defines page layout, user interactions, and orchestration of backend access. Streamlit configuration and visual presentation are separated from application code:

- `app.py`
- `.streamlit/config.toml`
- `assets/styles.css`

#### Streamlit Runtime Boundary

The app depends on Streamlit’s server-driven execution model: browser events trigger reruns of Python code, with Streamlit responsible for UI rendering and session behavior. Runtime-specific settings, including server/theme options, are located in:

- `.streamlit/config.toml`
- `.streamlit/secrets.toml`

Secrets should remain a deployment/runtime boundary rather than being embedded in `app.py`.

#### Firebase Integration Boundary

Firebase configuration is isolated in `firebase_config.py`, making it the likely integration point for authentication, database, storage, or other Firebase services. Application code in `app.py` should consume initialized Firebase clients or service functions from this module rather than directly coupling UI logic to Firebase SDK setup.

- `firebase_config.py`
- `app.py`
- `.streamlit/secrets.toml`

Primary flow: Streamlit UI in `app.py` receives user input, invokes Firebase-backed operations through `firebase_config.py`, and renders returned state or errors.

#### Styling and Static Assets

Presentation assets are repository-local and separate from Python behavior. The Streamlit application can load custom CSS from the assets directory to supplement native Streamlit widgets.

- `assets/styles.css`
- `app.py`

#### Dependencies and Deployment

Python package dependencies are declared in `requirements.txt`; the selected interpreter version is pinned by `.python-version`. Deployment instructions are maintained separately in `DEPLOYMENT.md`, while local containerized development is supported through the devcontainer configuration.

- `requirements.txt`
- `.python-version`
- `DEPLOYMENT.md`
- `.devcontainer/devcontainer.json`

The material infrastructure is therefore a Streamlit-hosted Python process with Firebase as the external service dependency. Environment-specific credentials/configuration flow through Streamlit secrets rather than source-controlled application modules.
