+🔧 TOKEN FIX IMPLEMENTED
+
+✅ Changed from HF_DEMO to HF_TOKEN in all files:
+- app.py: os.getenv("HF_TOKEN")
+- utils.py: os.getenv("HF_TOKEN")  
+- config.py: TOKEN_ENV_VAR = "HF_TOKEN"
+
+📍 SETUP INSTRUCTIONS:
+
+1. In your Hugging Face Space settings:
+   - Go to Settings → Variables & secrets
+   - Add a new secret with name: HF_TOKEN
+   - Value: your_huggingface_token_here
+
+2. The token should now be properly recognized!
+
+🔄 DEPLOYMENT STEPS:
+1. Update the files in your Space
+2. Restart the Space (if needed)
+3. The app should now work with HF_TOKEN
+
+📝 NOTES:
+- HF_TOKEN is the standard Hugging Face token name
+- This matches what Hugging Face Spaces expects by default
+- All references to HF_DEMO have been replaced with HF_TOKEN
+
+🗑️ FILE MANAGEMENT:
+- You can safely delete this RESPONSE_INSTRUCTIONS.txt file after reading
+- This keeps your main code files clean
+- Future responses will be in separate files like this
+
+**Key changes made:**
+
+1. ✅ **Token Name Fixed**: Changed all references from `HF_DEMO` to `HF_TOKEN`
+2. ✅ **Updated All Files**: Modified `app.py`, `utils.py`, and `config.py`
+3. ✅ **Added Config**: Added `TOKEN_ENV_VAR = "HF_TOKEN"` to config for consistency
+4. ✅ **Separate Response File**: Created `RESPONSE_INSTRUCTIONS.txt` for you to read and delete
+
+**What you need to do:**
+1. Make sure your Hugging Face Space has `HF_TOKEN` as the secret name (not `HF_DEMO`)
+2. Update the files in your Space
+3. The app should now work properly!
+
+The `HF_TOKEN` is the standard environment variable name that Hugging Face Spaces automatically recognizes and makes available to your app.
