- Moved the useIsMobile hook import to the correct position in conditional-layout.tsx.
- Added type="button" to the ThemeToggleSwitch button for better accessibility.
- Introduced truncateString utility in UserInfo component to limit email display length.
- Set Image component in UserInfo to unoptimized for performance improvement.
