Build a weather dashboard app called "SkyLens".
- Large hero card: city name, big temperature, weather icon, condition text
- Secondary stats: Feels Like, Humidity, Wind Speed, UV Index, Visibility, Pressure — in a grid
- 5-day forecast row with day, icon, high/low temps
- Hourly forecast horizontal scroll (12 hours)
- Search bar to enter city (use placeholder data, no real API needed)
- Background gradient changes based on weather condition (sunny=warm, rainy=blue-grey, night=dark)
- Unit toggle: Celsius / Fahrenheit
Design: glassmorphism cards, gradient backgrounds, white text, soft blur effects.
