+app.py - Simple Weather Forecast Web App (Demo)
+------------------------------------------------
+This is a beginner-friendly Gradio app for Hugging Face Spaces.
+
+⚠️ NOTE:
+This demo does not use real-time weather APIs (so no API key needed).
+It generates a mock forecast based on simple rules.
+You can later connect it to real APIs like OpenWeatherMap.
+
+How to run (in Hugging Face Spaces or Colab):
+1. pip install -r requirements.txt
+2. python app.py
+3. Open the public link.
