# 🧬 Interdependence Concept Game (Streamlit on Hugging Face Spaces)

An interactive, staged practice tool for **negative feedback loops** and **interdependence of body systems**.  
Scenarios included:
- **Blood Pressure (Hypotension)** → Baroreflex (nervous), RAAS (renal)
- **Glucose (Post-meal Hyperglycemia)** → Insulin loop, Kidney overflow/excretion
- **Temperature (Hypothermia)** → Shivering (somatic motor), Skin vessel loop (autonomic)

Each loop walks students through:
1) **Build the loop** (Sensor → Control Center → Effector)  
2) **Sensor → Control** signaling (type, receptor location, primary transport/gradient)  
3) **Control → Effector** signaling  
4) **Outcome** (loop-specific response)

When both loops in a scenario are completed, students can download a **PDF certificate** (requires `reportlab`).

## ▶️ Run in Hugging Face Spaces (Docker mode)

This Space is set up to run via **Docker**. The container launches Streamlit with:

```bash
streamlit run app.py --server.port=$PORT --server.address=0.0.0.0
