This pull request delivers a comprehensive mobile-first user experience overhaul for the NexusReader SaaS platform, specifically optimizing the Reader Canvas, D3.js Knowledge Graph representation, Dashboard card grid layout, and the application-wide navigation shell on mobile viewports (< 768px).
### Key Enhancements:
1. **Interactive Three-Tab Bottom Navigation**: Added premium, frosted glassy bottom-bar for mobile viewports to switch between standard reading, D3.js graph visual workspace, and structural concept reviews/quizzes.
2. **Contextual Floating Action Button (FAB)**: Introduced the AI Assistant FAB on mobile canvas layout with responsive animation, state-synchronization to trigger corresponding quiz views, and pulsing badge notification when new quizzes are dynamically generated.
3. **Adaptive D3.js Simulation & Rendering**: Integrated `setMobileMode(isMobile)` logic inside the D3 simulation engine, optimizing forces, rendering compact glyph pills, and installing auto-resize observers.
4. **Architectural & Native AOT Cleanliness**: Clean separation of layouts, fully scoped CSS configurations, functional-safe event orchestration inside `IReaderInteractionService`, and zero compiler errors.
