+### 🚀 Complete Codebase Optimization & Cleanup
+
+#### Asset Optimization
+
+- **Image Compression**: Optimized all large images for web performance
+  - `sayak.png`: 2.5MB → 74KB (97% reduction)
+  - `epic-learning-sync.png`: 239KB → 71KB (70% reduction)
+  - `zeomed-services.png`: 231KB → 44KB (81% reduction)
+  - Converted PNG to optimized JPEG format where appropriate
+  - Maintained image quality while dramatically reducing file sizes
+
+#### React 19 Optimization
+
+- **React Import Cleanup**: Removed unnecessary React imports from 29 TSX files
+  - Leveraged React 19's automatic JSX transform
+  - Removed `React.FC` typing in favor of cleaner function declarations
+  - Updated `React.createElement` calls to JSX syntax in test files
+  - Optimized `index.tsx` to use named imports (`StrictMode`)
+
+#### Dependency Management
+
+- **Unused Dependency Removal**: Eliminated 56 unused packages
+  - Removed `@react-three/fiber`, `@react-three/drei`, `three` packages
+  - Cleaned up Three.js mocks from test setup
+  - Updated Vite configuration to remove three-vendors chunk
+  - Reduced bundle complexity and improved build performance
+
+#### Bundle Optimization
+
+- **Enhanced Chunk Splitting**: Improved from previous optimization
+  - Removed unused three-vendors chunk
+  - Maintained optimized vendor chunks:
+    - react-core: 185KB (React and ReactDOM)
+    - react-router: 31KB (React Router)
+    - markdown-vendors: 156KB (Markdown processing)
+    - vendors: 230KB (Other libraries)
+
+#### Code Quality Improvements
+
+- **Test File Optimization**: Updated all test files to React 19 standards
+- **Configuration Cleanup**: Streamlined build and development configurations
+- **Type Safety**: Maintained full TypeScript compliance throughout optimization
+
+#### Performance Results
+
+- **Build Time**: Consistent ~1.67s build performance
+- **Bundle Size**: Maintained efficient 18MB total build size
+- **Asset Loading**: Significantly faster image loading due to compression
+- **Development Experience**: Cleaner, more maintainable codebase
