- **Frontend (Flutter)**
- Optimize for Google TV: Force Landscape mode, disable touchscreen requirement, and set TV Dashboard as default home.
- Weather Widget:
- Add Daily Max/Min temperature ('최고/최저').
- Add Air Quality Index (AQI) with visual indicator ('미세먼지').
- Increase font sizes and adjust layout to match Digital Clock style.
- Implement 1-hour auto-refresh timer.
- Model: Update WeatherInfo to support tempMin, tempMax, and aqi.
- **Backend (Node.js)**
- Weather API (/api/weather):
- Implement daily forecast aggregation logic (Seoul Time KST) to calculate accurate daily High/Low.
- Integrate OpenWeatherMap Air Pollution API to fetch AQI.
