This PR implements a comprehensive mobile-first design overhaul for the Reader, Dashboard, and Navigation layouts.
### Key Accomplishments
1. **Dynamic Viewport Synchronization**: Installed robust `ResizeObserver` listener on the client side with automatic reactive toggling of `platform-mobile`/`platform-desktop` CSS classes.
2. **Tab Controller & Visibility Fixes**: Refactored visibility constraints in `ReaderLayout.razor.css` to prevent layout clipping and DOM bloat. Standardized the mobile tab content selectors to ensure active views display perfectly.
3. **D3.js Graph Stabilization**:
* Added checks to bypass resize callbacks when the graph container is hidden (`clientWidth <= 0` or `clientHeight <= 0`).
* Guarded coordination ticks, node focus transformations, and zoom transitions against `NaN` parameters.
4. **Interactive Mobile UX Enhancements**: Optimized touch target sizing (44px target bounds) and interactive transitions for a state-of-the-art visual presentation.
This has been successfully compiled and verified against the standard .NET 10 compilation gates.

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.

# gamified Concepts Map Dashboard, Architecture Cleanup, & CSS Unification
This Pull Request completes the gamified **Concepts Map** interactive experience and executes a strict visual and architectural clean-up of the **NexusReader SaaS** platform by consolidating styling around the centralized **Nexus Neon** design system, enforcing Native AOT-compliant scoped-CSS, and resolving style drift.
---
### 🚀 Key Implementations
#### 1. Gamified Interactive Concepts Map Dashboard
* **Dynamic Skill-Tree Visualizer:** Implemented a gamified node-based interactive tree that reads concept connections dynamically, rendering progress nodes, unlocked/locked states, and active visual connection lines.
* **Premium UX Details:** Integrated high-fidelity hover effects, detailed sidebar popovers showing unlocked stats/summaries, and smooth parallax backdrops.
* **Secure Multi-Tenant Gating:** Hardened data queries using explicit `TenantId` gating to ensure complete layout isolation between system tenants.
#### 2. Architecture & Service Optimization
* **Service Abstraction (`IConceptsMapService`):** Introduced a clean service interface decoupled from the UI layers.
* **Polyglot Fallback Implementations:**
- **WasmConceptsMapService:** Implements efficient client-side fetching with error recovery/loading states.
- **ServerConceptsMapService:** Handles deep database graph mapping, relationship resolution, and multi-tenant checks.
* **CQRS Integrity:** Enforced the CQRS Result Pattern by using `MediatR` handlers to fetch data structures instead of placing database queries in UI modules.
#### 3. Nexus Neon CSS Unification & Zero-Style-Tag Standards
* **Central Design Tokens:** Solidified typography (`Inter` / `Merriweather`), primary brand green hues (`var(--nexus-neon)` at `#00ff99`), and glow variables inside the global `app.css`.
* **Zero Inline Style Tags:** Standardized all dashboard modules by completely eliminating inline `<style>` blocks in favor of scoped `.razor.css` companion files.
* **Consolidated Buttons & Glass Panels:**
- Standardized `.btn-nexus`, `.btn-nexus-primary`, and `.btn-nexus-secondary` throughout header/footer/card operations.
- Removed duplicate `.glass-panel` background, blur, and support-declaration overrides, making components cleanly inherit standard global styles.
* **Eliminated Brand Splitting:** Resolved legacy purple-indigo user avatar and conversation bubble gradients inside the AI Intelligence Hub (`Intelligence.razor.css`), migrating them to premium glassmorphic surfaces (`rgba(255, 255, 255, 0.05)`) contrasting beautifully against the emerald green AI theme.
---
### 🧪 Verification & Build Gate Status
* **Successful Compilation Check:** Run `dotnet build NexusReader.slnx --no-restore` from the workspace root. Flawlessly succeeded with **zero compilation errors** (`Liczba błędów: 0`) under target `.NET 10`.
* **Verified Skills Synchrony:** The companion design guidelines skill (`nexus-ui-engine/SKILL.md`) has been fully updated to secure these layout and styling conventions for future dashboard features.
