New chat started from template Adding next-themes

Your app is fully configured and ready to run. The setup includes:

• ThemeProvider properly configured in layout.tsx with next-themes for dark/light mode support
• Two theme components: ThemeToggle (simple toggle) and ThemeSwitcher (dropdown with system option)
• All required dependencies installed, including next-themes v0.4.6
• Working page that demonstrates the theme toggle in action

The app is production-ready with proper hydration handling (using suppressHydrationWarning and mounted state checks) to prevent theme flashing. You can now preview it and switch between light, dark, and system themes seamlessly.
