+# 🧩 IIP Grading — Public Loader for Private Static Space
+
+This Space securely **proxies** your private static app hosted at  
+`https://cheekeong2025-iip-grading.static.hf.space`  
+without revealing its source code or assets.
+
+## 🔧 How It Works
+- The loader runs a small **FastAPI + httpx** proxy.
+- It uses your private Hugging Face token (`HF_TOKEN`) to fetch content.
+- End users only interact with this public loader Space, not the private one.
+
+## 🔐 Required Secrets (set under “Settings → Repository secrets”)
+
+| Secret Name | Example Value | Description |
+|--------------|---------------|-------------|
+| `PRIVATE_STATIC_URL` | `https://cheekeong2025-iip-grading.static.hf.space` | URL of your private static Space |
+| `HF_TOKEN` | `hf_xxxxxxxxxxxxxxxxxxxxxxx` | Hugging Face token with read access to that private Space |
+
+## 🚀 Deployment
+1. Create a **new public Space** → Type: `Docker`.
+2. Upload:
