- Added theme variables for light and dark modes in viewer-template.html. - Created a custom hook `useTheme` to manage theme preferences and resolve the current theme based on user selection or system settings. - Introduced `ThemeToggle` component to allow users to switch between themes. - Updated `Header` component to include the `ThemeToggle` and pass theme preference and change handler. - Modified `App` component to integrate theme management and pass relevant props to child components.
