🌗 How Theme Toggle Works

This project uses React Context API to store the current theme (light or dark) globally.

Steps involved:

1. Create a ThemeContext
2. Wrap the application with ThemeContext Provider
3. Store the theme using useState
4. Access theme in components using useContext
5. Toggle the theme using a button
6. Apply Tailwind's dark mode classes

This approach avoids passing props through multiple components.
