+# EXPLANATION
+# The UI improvements transform the app into a professional, modern interface:
+# 1. **Centered Layout**: Custom CSS limits max-width to 900px and centers content
+# 2. **Professional Theme**: Gradient header, white containers with shadows, soft gray background
+# 3. **Chat-Style Display**: Answers appear in rounded, shaded containers like chat bubbles
+# 4. **Enhanced Sidebar**: Organized into clear sections (About App, Settings, Developer info)  
+# 5. **Better Visual Hierarchy**: Icons, proper spacing, styled buttons and containers
+# 6. **Responsive Design**: Uses columns for button centering and better mobile experience
