This PR introduces a major optimization of graph dynamics, immersive reading experience, and architectural stabilization. ### 🚀 Key Improvements - **Knowledge Graph (Fix #16)**: - Implemented smooth D3.js transitions using the General Update Pattern. - Added "Neon Flash" entry animations and dynamic node dimming for better focus. - **Immersive Reader (Fix #12)**: - Standardized centered layout (`max-width: 800px`) with **Merriweather** typography. - Optimized line-height and letter-spacing for premium readability. - **Technical Code Blocks (Fix #20)**: - High-contrast dark containers for code snippets. - **JetBrains Mono** integration and neon-accented scrollbars. - **Architectural Stabilization**: - Enforced a strict **'no async void'** policy in UI services using `Func<Task>`. - Resolved WASM runtime DI errors by implementing dummy service proxies for server-side dependencies. - Replaced generic 'Not Found' message with a branded Nexus preloader. Fixes #7, Fixes #12, Fixes #16, Fixes #20. Reviewed-on: #19 Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Co-committed-by: Marek Jasiński <jasins.marek@gmail.com>

# UI Standards
|
|
|
|
- **Atomic Design:**
|
|
- Build reusable components in `NexusReader.UI.Shared/Components`.
|
|
- `Atoms`: Base elements (`NexusButton`, `NexusIcon`, `NexusTypography`).
|
|
- `Molecules`: Small groups (`AiAssistantBubble`, `KnowledgeCheck`).
|
|
- `Organisms`: High-level sections (`KnowledgeGraph`, `ReaderCanvas`).
|
|
|
|
- **Styling & Isolation:**
|
|
- Mandatory use of scoped CSS (`.razor.css`).
|
|
- No global CSS except for design tokens in `app.css`.
|
|
- Use `::deep` only when absolutely necessary to style child components.
|
|
|
|
- **Design System (Nexus Neon):**
|
|
- **Color Palette:**
|
|
- Primary Accent: `--nexus-neon` (`#00ff99`) - Used for borders, highlights, and icons.
|
|
- Dark Mode: `--nexus-bg` (`#0a0a0a`), `--nexus-card` (`#141414`).
|
|
- Light Mode: `--nexus-bg` (`#f8f9fa`), `--nexus-card` (`#ffffff`).
|
|
- **Typography:**
|
|
- UI Elements: `Inter` (Sans-Serif) for controls, menus, and labels.
|
|
- Reading Content: `Merriweather` (Serif) with `line-height: 1.65` and `letter-spacing: -0.01em` for high readability.
|
|
- **Effects:**
|
|
- Subtle neon glows (`box-shadow: 0 0 15px rgba(0, 255, 153, 0.3)`).
|
|
- Glassmorphism for overlays and modals.
|
|
|
|
- **Adaptive Layouts:**
|
|
- Support `.platform-mobile` and `.platform-desktop` context classes.
|
|
- Handle safe-area insets (`--safe-area-inset-*`) for mobile devices.
|
|
- **Immersive Reader (Zen Mode):**
|
|
- Centered content flow: `max-width: 800px`, `margin: 0 auto`.
|
|
- Paper-white background: `#F9F9F9` for light mode reader canvas.
|
|
- Dedicated Scrollbars: Custom styled, thin scrollbars with `--nexus-neon` accents.
|
|
- Reachability: Large `padding-bottom` (e.g., `15rem`) to ensure comfortable reading of end-of-page content.
|
|
|
|
- **Accessibility (A11y):**
|
|
- Touch Targets: Min `44x44px` on mobile (enforced via CSS variables).
|
|
- Contrast: Minimum ratio of 4.5:1.
|
|
- Semantic HTML: Use appropriate tags (`<button>`, `<article>`, `<nav>`).
|
|
|
|
- **Interactive Flow:**
|
|
- AI Assistant interactions must be non-blocking and smoothly transition using CSS animations.
|
|
- Interactive elements must have clear `:hover`, `:active`, and `:focus` states. |
