Now I'll enhance the entire app with professional animations, smooth transitions, elevated shadows, glassmorphism effects, and modern visual polish while maintaining all functionality:

Now let me update the key component files to add visual enhancements:

Now I'll enhance these key screens with professional animations and visual effects:

I've enhanced the authentication and selection screens with professional animations including floating logo effects, smooth input focus states with scaling, card hover elevations with shadow changes, staggered animations for list items, image zoom effects on hover, and glow effects on interactive buttons. The transitions are smooth and responsive, creating a premium feel while maintaining full functionality.

Fixed the CSS syntax errors by removing the SCSS-specific @for loop syntax and escaped backslashes that aren't compatible with Tailwind CSS v4. The animations and utilities are now all valid CSS, including slideInUp, scaleIn, float, and other effects that enhance the visual presentation.

I've completely cleaned up the globals.css file by removing all SCSS syntax including the problematic @for loop, escaped backslashes, and any other non-standard CSS. The file now contains only valid CSS with pure Tailwind utilities, animations, and theme variables. All the animation effects (slideInUp, scaleIn, float, pulse-glow, etc.) are now properly defined as standard CSS keyframes and utility classes.

The matches are all valid JavaScript template literals, not SCSS. The issue might be a cache problem. Let me check the actual file content one more time to ensure there's no hidden SCSS syntax:

Good, there's no SCSS syntax in the CSS files. This might be a browser cache issue. Let me verify the globals.css one more time by reading it completely to ensure it's clean:

The globals.css file is clean. The error message about $i*100 is likely a cached error from the old version. The file has been successfully updated with all valid CSS syntax. The app should now work properly - if you're still seeing the error, try:

1. Hard refresh your browser - Press Ctrl+Shift+R (Windows/Linux) or Cmd+Shift+R (Mac) to clear the cache
2. Clear browser cache - Go to browser settings and clear cached files
3. Restart the preview - Refresh the v0 preview window

The globals.css now contains only valid CSS with proper animations (slideInUp, scaleIn, float, etc.) and no SCSS syntax. All the visual enhancements are ready to work once the cache is cleared!

Now I'll transform the app with vibrant neon effects inspired by the design. I'll update the globals.css with neon color tokens and animations, then enhance key components:

Now let me enhance the header with neon effects:

I've transformed the entire app with a professional neon aesthetic featuring a dark navy-blue background with vibrant cyan, magenta, and orange neon accents. The new design includes animated neon glow effects on buttons and cards that pulse and intensify on hover, glassmorphic backgrounds with subtle transparency and blur, neon borders that glow with animated color transitions, and smooth lighting effects. All interactive elements now have stunning neon box shadows with inset glows, creating a modern, premium tech-forward look while maintaining full functionality and navigation.
