Theme Customization

The library uses a centralized AppStyle singleton for theming:

// Toggle theme
AppStyle.toggleTheme()

// Check current theme
if (AppStyle.isDark) {
    // Dark mode
}

// Access theme colors
color: AppStyle.primaryColor
color: AppStyle.textColor
color: AppStyle.backgroundColor
