Enhancements & Bug Fixes

404 Page Enhancement

Modernized the NotFoundPage.jsx to provide a responsive, algorithm-themed 404 page.
Key Improvements:

• Centered glassmorphism card with theme-aware colors
• Pulsing 404 title, animated divider, and fade-in effects
• Dynamic messages using algorithm/graph terminology
• Clear navigation: Back to Home, View Docs, and quick-links to algorithm pages
• Fully responsive and accessible

GraphVisualizer Bug Fix

Problem: Runtime Error: useAlgorithmSettings must be used within an AlgorithmSettingsProvider
Root Cause: GraphVisualizer wasn't wrapped with the required context provider, but ControlPanel uses useAlgorithmSettings

Solution: Wrapped GraphVisualizer with AlgorithmSettingsProvider

Result:

• Fixed runtime error; page no longer crashes
• ControlPanel works as expected
• No breaking changes
• Proper context hierarchy established
