🎯 Major Achievements:
- Standardized 193+ SCSS imports across all libraries
- Created 12 independent Git repositories with clean submodule structure
- Eliminated relative path dependencies for true library portability
- Added comprehensive consumer integration documentation

📦 Libraries Successfully Published:
• ui-design-system (foundation)
• ui-essentials (components)
• shared-utils (utilities)
• auth-client (authentication)
• ui-landing-pages (marketing components)
• ui-code-display (syntax highlighting)
• ui-accessibility (WCAG compliance)
• hcl-studio (color management)
• ui-animations (CSS animations)
• ui-backgrounds (background effects)
• ui-font-manager (typography)
• ui-data-utils (data manipulation)

🔧 Technical Improvements:
- All SCSS imports now use standardized 'ui-design-system/' paths
- Libraries work independently as Git submodules
- Consumer projects can selectively include only needed libraries
- Professional Git history with initial commits for each library
- Updated integration guides with step-by-step workflows

📋 Documentation Added:
- CONSUMER_INTEGRATION_GUIDE.md - Complete setup instructions
- Updated SUBMODULE_INTEGRATION_GUIDE.md - Enhanced with dependency info
- Library-specific README files for all repositories

🚀 Ready for Production:
- All libraries pushed to https://git.sky-ai.com/jules/*
- Clean separation of concerns across library boundaries
- Independent versioning and release cycles possible
- Optimal structure for LLM analysis and maintenance

This completes the monorepo-to-submodule transformation, making the SSuite library ecosystem ready for professional distribution and consumption.

-## Development Notes
+## Development Workflow
 
-- All libraries use Angular 19.2+ with strict TypeScript configuration
+### Component Development
+1. **New components**: Add to appropriate category in `ui-essentials/src/lib/components/`
+2. **Export new components**: Update category `index.ts` files  
+3. **Demo components**: Create matching demo in `demo-ui-essentials/src/app/demos/`
+4. **Routing**: Add demo routes to `demos.routes.ts`
+
+### Build Dependencies
 - Libraries must be built before being consumed by other projects
-- Use `ng generate` commands within library contexts for scaffolding
+- Demo application depends on built library artifacts in `dist/`
+- Use watch mode (`ng build --watch`) for development iterations
+
+### Library Development
+- All libraries use Angular 19.2+ with strict TypeScript configuration
+- Use `ng generate` commands within library contexts for scaffolding  
 - Libraries are publishable to npm after building to `dist/` directory
-- Testing uses Karma with Jasmine framework
+- Testing uses Karma with Jasmine framework
+- FontAwesome icons integrated via `@fortawesome/angular-fontawesome`

+# Component Creation Template
+
+## ⚠️ CRITICAL RESTRICTIONS ⚠️
+
+### DO NOT MODIFY EXISTING COMPONENTS
+- **NEVER** alter Angular or SCSS code of already built components
+- **NEVER** change existing component files unless explicitly instructed
+- **ONLY** create NEW components as specified in the task
+- **ONLY** update integration files (routes, menu, public API) to add references to new components
+- If asked to modify an existing component, REQUEST CLARIFICATION before proceeding
+- Existing components are PRODUCTION CODE and must remain untouched
+
+### Protected Files and Directories
+The following should NEVER be modified without explicit permission:
+- Any existing component files in `@projects/ui-essentials/src/lib/components/`
+- Any existing demo files in `@projects/demo-ui-essentials/src/app/demos/`
+- Only ADD new entries to:
+  - `demos.routes.ts` (add new cases, don't modify existing)
+  - `dashboard.component.ts` (add new menu items, don't modify existing)
+  - `public-api.ts` (add new exports, don't modify existing)
+
+---
+
+## Component Creation Task Template
+
+### 1. Component Selection
+
+  - Alert/Notification
+
+
+### 2. Pre-Development Checklist
+- [ ] Check if similar component exists in codebase
+- [ ] Review existing components in same category for patterns
+- [ ] Identify required design tokens from semantic layer
+- [ ] Plan component API (inputs, outputs, content projection)
+- [ ] **CONFIRM: This is a NEW component, not a modification of an existing one**
+
+### 3. Implementation Steps
+
+#### Step 1: Create Component Structure
+**Location:** `@projects/ui-essentials/src/lib/components/[category]/[component-name]/`
+
+Create these NEW files (do not overwrite existing):
+- `[component-name].component.ts`
+- `[component-name].component.scss`
+- `index.ts` (barrel export)
+
+#### Step 2: SCSS Implementation
+Follow the **Design Token Guidelines** below to create component styles.
+
+#### Step 3: Angular Component Implementation
+Follow the **Angular Component Guidelines** below.
+
+#### Step 4: Create Demo Component
+**Location:** `@projects/demo-ui-essentials/src/app/demos/[component-name]-demo/`
+- Create NEW demo component showing all variants, sizes, and states
+- Include interactive examples and code snippets
+- Follow existing demo patterns
+
+#### Step 5: Integration Updates (ADDITIVE ONLY)
+
+##### A. Update Routes (ADD ONLY - DO NOT MODIFY EXISTING)
+**File:** `@projects/demo-ui-essentials/src/app/demos/demos.routes.ts`
+```typescript
+// Add import - DO NOT MODIFY EXISTING IMPORTS
+import { [ComponentName]DemoComponent } from './[component-name]-demo/[component-name]-demo.component';
+
+// Add to template switch case - DO NOT MODIFY EXISTING CASES
+@case ("[component-name]") {
+    <ui-[component-name]-demo></ui-[component-name]-demo>
+}
+
+// Add to imports array - DO NOT REMOVE OR MODIFY EXISTING ENTRIES
+imports: [...existing, [ComponentName]DemoComponent]
+```
+
+##### B. Update Dashboard Menu (ADD ONLY - DO NOT MODIFY EXISTING)
+**File:** `@projects/demo-ui-essentials/src/app/features/dashboard/dashboard.component.ts`
+```typescript
+// Import appropriate FontAwesome icon - DO NOT MODIFY EXISTING IMPORTS
+import { faIconName } from '@fortawesome/free-solid-svg-icons';
+
+// Add in ngOnInit() - DO NOT MODIFY EXISTING MENU ITEMS
+this.addMenuItem("[component-id]", "[Component Label]", this.faIconName);
+```
+
+##### C. Update Public API (ADD ONLY - DO NOT MODIFY EXISTING)
+**File:** `@projects/ui-essentials/src/public-api.ts`
+```typescript
+// Add export in appropriate section - DO NOT MODIFY EXISTING EXPORTS
+export * from './lib/components/[category]/[component-name]';
+```
+
+### ⚠️ INTEGRATION WARNING ⚠️
+When updating integration files:
+- **ONLY ADD** new entries
+- **NEVER DELETE** existing entries
+- **NEVER MODIFY** existing entries
+- **PRESERVE** all existing formatting and structure
+- **TEST** that existing components still work after changes
+
+---
+
+## Design Token Guidelines ⚠️ CRITICAL: ONLY USE EXISTING TOKENS ⚠️
+
+### MANDATORY: Import and Use Semantic Tokens
+```scss
+@use '@projects/shared-ui/src/styles/semantic' as *;

+
+### 🚨 CRITICAL TOKEN VALIDATION 🚨
+
+#### ❌ COMMON MISTAKES TO AVOID:
+```scss
+// WRONG - These tokens DON'T EXIST:
+font-size: $semantic-typography-heading-h3;           // This is a MAP, not a single value!
+padding: $semantic-spacing-layout-xs;                 // DOESN'T EXIST
+box-shadow: $semantic-shadow-card-featured;           // DOESN'T EXIST  
+border-radius: $semantic-border-radius-xs;            // DOESN'T EXIST
+transition: $semantic-motion-duration-medium;         // DOESN'T EXIST
+background: $semantic-color-background-primary;       // DOESN'T EXIST
+
+// WRONG - Hardcoded values:
+padding: 16px;                                        // Use $semantic-spacing-component-md
+color: #333333;                                       // Use $semantic-color-text-primary
+border-radius: 8px;                                   // Use $semantic-border-radius-md
+```
+
+#### ✅ CORRECT USAGE:
+```scss
+// RIGHT - Use map-get for typography maps:
+font-size: map-get($semantic-typography-heading-h3, font-size);
+font-weight: map-get($semantic-typography-heading-h3, font-weight);
+
+// RIGHT - Use single value tokens directly:
+padding: $semantic-spacing-component-md;
+color: $semantic-color-text-primary;
+border-radius: $semantic-border-card-radius;
+box-shadow: $semantic-shadow-elevation-2;
+```
+
+### ⚠️ MAP USAGE WARNING ⚠️
+These tokens are **MAPS** and require `map-get()`:
+- `$semantic-typography-heading-*` (h1, h2, h3, h4, h5)
+- `$semantic-typography-body-*` (large, medium, small)  
+- `$semantic-typography-button-*` (large, medium, small)
+- `$semantic-typography-label`
+- `$semantic-typography-input`
+- `$semantic-typography-caption`
+
+**Always extract individual properties:**
+```scss
+// CORRECT MAP USAGE:
+font-family: map-get($semantic-typography-body-medium, font-family);
+font-size: map-get($semantic-typography-body-medium, font-size);
+font-weight: map-get($semantic-typography-body-medium, font-weight);
+line-height: map-get($semantic-typography-body-medium, line-height);
+```
+
+### Expected Deliverables:
+1. **SCSS file** properly structured with ONLY existing semantic tokens
+2. **BEM methodology** consistently applied throughout
+3. **Responsive design** using actual breakpoint tokens
+4. **Interactive states** (hover, focus, active) defined with real tokens
+5. **Zero hardcoded values** - everything uses verified design tokens
+6. **Proper map usage** for typography tokens
+7. **Comments** explaining major sections if complex
+
+### Quality Checklist:
+- [ ] All colors use actual `$semantic-color-*` tokens
+- [ ] All spacing uses actual `$semantic-spacing-*` tokens  
+- [ ] All typography uses proper map-get() for maps or single tokens
+- [ ] All shadows use actual `$semantic-shadow-*` tokens
+- [ ] All borders use actual `$semantic-border-*` tokens
+- [ ] All motion uses actual `$semantic-motion-*` tokens
+- [ ] **No hardcoded values anywhere**
+- [ ] **No invented token names**
+- [ ] BEM naming convention followed
+- [ ] Responsive breakpoints implemented with actual tokens
+- [ ] File saved in correct directory

+
+## Angular Component Guidelines (Enhanced)
+
+### Angular 19+ Development Standards:
+
+#### TEMPLATES:
+- Use inline templates in @Component decorator
+- Use new control flow syntax: @if, @for, @switch (NOT *ngIf, *ngFor)
+- Use @defer for lazy loading where appropriate
+- Put stylesheets in a separate scss file to the component
+
+#### STYLING:
+- Import design tokens: @use '@projects/shared-ui/src/styles/semantic' as *;
+- **CRITICAL:** Ensure correct semantic tokens are used. Do not invent new ones.
+- **If a semantic variable is required but doesn't exist, ASK FOR INSTRUCTION**
+- NO hardcoded values - use only design tokens for colors, spacing, typography, breakpoints
+- Follow BEM naming convention for class names
+- Use SCSS nesting judiciously (max 3 levels)
+- Prefer mixins and functions from the design system
+
+#### TYPESCRIPT:
+- Use standalone components (no NgModules)
+- Prefer signals over observables for state management
+- Use inject() function over constructor injection
+- Strong typing everywhere - avoid 'any'
+- Use readonly where applicable
+- Implement OnPush change detection by default
+
+#### STRUCTURE:
+- Feature-based folder structure
+- Barrel exports for clean imports
+- Smart/presentational component pattern
+- Services should be provided in root unless scoped needed
+
+### Component Template

+
+## 🚨 FINAL TOKEN VALIDATION 🚨
+
+### Before Implementation:
+1. **VERIFY** every token used exists in the reference above
+2. **ASK FOR HELP** if you need a token that doesn't exist
+3. **TEST** build process to catch any invalid tokens
+4. **NEVER GUESS** or invent token names
+
+### If you need a token that doesn't exist:
+- **STOP** implementation
+- **ASK** "This component needs [specific token type] but I don't see one available. Should I [alternative approach] or do you have guidance?"
+- **WAIT** for direction rather than inventing tokens
+
+This template provides a comprehensive guide for creating consistent, high-quality NEW components that integrate seamlessly with the existing design system without affecting any existing code, **and most importantly, without using non-existent tokens that would cause build failures**.

+# Angular Library Consumer Integration Guide
+
+## 🚀 Complete Guide: Creating a New Angular Project with SSuite Libraries
+
+This guide shows you how to create a fresh Angular project and integrate any combination of the 12 SSuite libraries using Git submodules.
+
+---
+
+## 📋 Prerequisites
+
+- **Node.js 18+** and npm
+- **Angular CLI** (`npm install -g @angular/cli`)
+- **Git** configured with access to `git.sky-ai.com`
+
+---
+
+## 🏗️ Step 1: Create New Angular Project
+
+```bash
+# Create new Angular project
+ng new my-awesome-app
+cd my-awesome-app
+
+# Create libs directory for submodules
+mkdir libs
+```
+
+---
+
+## 📦 Step 2: Choose Your Libraries
+
+Select libraries based on your needs:
+
+### 🎨 **Foundation (Required for most projects)**
+- **ui-design-system** - SCSS design tokens, colors, typography, fonts
+
+### 🛠️ **Essential Components**  
+- **ui-essentials** - Buttons, forms, tables, cards, navigation, etc.
+- **shared-utils** - Common utilities and shared services
+
+### 🎯 **Specialized Libraries**
+- **auth-client** - Authentication guards, services, interceptors
+- **ui-landing-pages** - Hero sections, pricing tables, testimonials
+- **ui-code-display** - Syntax highlighting for code blocks
+- **ui-accessibility** - WCAG compliance tools and utilities
+- **hcl-studio** - Advanced color management system
+
+### 🎭 **Enhancement Libraries**
+- **ui-animations** - CSS animation utilities
+- **ui-backgrounds** - Background generators and effects
+- **ui-font-manager** - Advanced font management
+- **ui-data-utils** - Data manipulation utilities
+
+---
+
+## ⚡ Step 3: Add Libraries as Submodules
+
+**IMPORTANT**: Always add `ui-design-system` first, as other libraries depend on it.
+
+### Minimal Setup (Design System + Components):
+```bash
+# Add foundation (required)
+git submodule add https://git.sky-ai.com/jules/ui-design-system.git libs/ui-design-system
+
+# Add essential components
+git submodule add https://git.sky-ai.com/jules/ui-essentials.git libs/ui-essentials
+git submodule add https://git.sky-ai.com/jules/shared-utils.git libs/shared-utils
+
+# Initialize submodules
+git submodule update --init --recursive
+```
+
+### Full-Featured Setup (All Libraries):
+```bash
+# Foundation (required first)
+git submodule add https://git.sky-ai.com/jules/ui-design-system.git libs/ui-design-system
+
+# Core libraries
+git submodule add https://git.sky-ai.com/jules/ui-essentials.git libs/ui-essentials
+git submodule add https://git.sky-ai.com/jules/shared-utils.git libs/shared-utils
+git submodule add https://git.sky-ai.com/jules/auth-client.git libs/auth-client
+
+# Specialized libraries
+git submodule add https://git.sky-ai.com/jules/ui-landing-pages.git libs/ui-landing-pages
+git submodule add https://git.sky-ai.com/jules/ui-code-display.git libs/ui-code-display
+git submodule add https://git.sky-ai.com/jules/ui-accessibility.git libs/ui-accessibility
+git submodule add https://git.sky-ai.com/jules/hcl-studio.git libs/hcl-studio
+
+# Enhancement libraries
+git submodule add https://git.sky-ai.com/jules/ui-animations.git libs/ui-animations
+git submodule add https://git.sky-ai.com/jules/ui-backgrounds.git libs/ui-backgrounds
+git submodule add https://git.sky-ai.com/jules/ui-font-manager.git libs/ui-font-manager
+git submodule add https://git.sky-ai.com/jules/ui-data-utils.git libs/ui-data-utils
+
+# Initialize all submodules
+git submodule update --init --recursive
+```
+
+---
+
+## 🔨 Step 4: Build Libraries
+
+Build libraries in dependency order:
+
+```bash
+# Build ui-design-system first (required by others)
+cd libs/ui-design-system
+npm install
+npm run build
+cd ../..
+
+# Build other libraries
+cd libs/ui-essentials && npm install && npm run build && cd ../..
+cd libs/shared-utils && npm install && npm run build && cd ../..
+cd libs/auth-client && npm install && npm run build && cd ../..
+
+# Continue for other libraries as needed...
+```
+
+### 📜 Automation Script:
+Create `build-libs.sh`:
+```bash
+#!/bin/bash
+echo "🏗️ Building all libraries..."
+
+# Array of libraries in dependency order
+LIBS=("ui-design-system" "shared-utils" "ui-essentials" "auth-client" "ui-landing-pages" "ui-code-display" "ui-accessibility" "hcl-studio" "ui-animations" "ui-backgrounds" "ui-font-manager" "ui-data-utils")
+
+for lib in "${LIBS[@]}"; do
+  if [ -d "libs/$lib" ]; then
+    echo "📦 Building $lib..."
+    cd libs/$lib
+    npm install
+    npm run build
+    cd ../..
+    echo "✅ $lib built successfully"
+  else
+    echo "⚠️ Skipping $lib (not found)"
+  fi
+done
+
+echo "🎉 All libraries built!"
+```
+
+Make executable: `chmod +x build-libs.sh && ./build-libs.sh`
+
+---
+
+## ⚙️ Step 5: Configure TypeScript Paths
+
+Update `tsconfig.json`:
+
+```json
+{
+  "compilerOptions": {
+    "baseUrl": "./",
+    "paths": {
+      // Foundation (required)
+      "ui-design-system": ["./libs/ui-design-system/dist"],
+      "ui-design-system/*": ["./libs/ui-design-system/dist/*", "./libs/ui-design-system/src/*"],
+      
+      // Core libraries
+      "ui-essentials": ["./libs/ui-essentials/dist"],
+      "ui-essentials/*": ["./libs/ui-essentials/dist/*"],
+      "shared-utils": ["./libs/shared-utils/dist"],

+      "auth-client": ["./libs/auth-client/dist"],
+      "auth-client/*": ["./libs/auth-client/dist/*"],
+      
+      // Specialized libraries
+      "ui-landing-pages": ["./libs/ui-landing-pages/dist"],
+      "ui-landing-pages/*": ["./libs/ui-landing-pages/dist/*"],

+      "ui-accessibility/*": ["./libs/ui-accessibility/dist/*"],
+      "hcl-studio": ["./libs/hcl-studio/dist"],
+      "hcl-studio/*": ["./libs/hcl-studio/dist/*"],
+      
+      // Enhancement libraries

+      "ui-data-utils/*": ["./libs/ui-data-utils/dist/*"]
+    }
+  }
+}
+```
+
+**Note**: The `ui-design-system/*` includes both `dist/*` and `src/*` to support SCSS imports.
+
+---
+
+## 🎨 Step 6: Import Styles
+
+### Option A: Complete Design System
+In your `src/styles.scss`:
+```scss
+// Complete design system (includes all tokens + fonts)
+@use 'ui-design-system/src/styles' as ui;
+
+// Optional: Additional component styles
+@use 'ui-animations/src/styles' as animations;
+@use 'ui-backgrounds/src/styles' as backgrounds;
+```
+
+### Option B: Selective Imports
+```scss
+// Just semantic tokens (most common)
+@use 'ui-design-system/src/styles/semantic' as tokens;
+
+// Or just base tokens
+@use 'ui-design-system/src/styles/base' as base;
+
+// Add specific libraries
+@use 'ui-accessibility/src/lib/utilities/a11y-utilities' as a11y;
+```
+
+---
+
+## 💻 Step 7: Use Libraries in Your Components
+
+### Example Component using multiple libraries:
+
+```typescript
+// src/app/app.component.ts
+import { Component } from '@angular/core';
+import { ButtonComponent } from 'ui-essentials';
+import { AuthService } from 'auth-client';
+import { HeroSectionComponent } from 'ui-landing-pages';
+import { CodeSnippetComponent } from 'ui-code-display';
+
+@Component({
+  selector: 'app-root',
+  standalone: true,
+  imports: [
+    ButtonComponent,
+    HeroSectionComponent, 
+    CodeSnippetComponent
+  ],
+  template: `
+    <div class="app-container">
+      <!-- Hero Section -->
+      <ui-hero-section
+        title="Welcome to My App"
+        subtitle="Built with SSuite Libraries"
+        [cta]="{ text: 'Get Started', action: 'primary' }">
+      </ui-hero-section>
+
+      <!-- Content Section -->
+      <main class="content">
+        <!-- Buttons from ui-essentials -->
+        <ui-button variant="primary" (click)="handleClick()">
+          Primary Action
+        </ui-button>
+        
+        <ui-button variant="secondary" [disabled]="!isLoggedIn">
+          Secondary Action  
+        </ui-button>
+
+        <!-- Code Display -->
+        <ui-code-snippet 
+          language="typescript"
+          [code]="exampleCode">
+        </ui-code-snippet>
+      </main>
+    </div>
+  `,
+  styles: [`
+    .app-container {
+      min-height: 100vh;
+    }
+    .content {
+      padding: 2rem;
+      max-width: 1200px;
+      margin: 0 auto;
+    }
+  `]
+})
+export class AppComponent {
+  isLoggedIn = false;
+  exampleCode = `
+import { ButtonComponent } from 'ui-essentials';
+import { AuthService } from 'auth-client';
+
+// Your code here...
+  `;
+
+  constructor(private auth: AuthService) {
+    this.isLoggedIn = this.auth.isAuthenticated();
+  }
+
+  handleClick() {
+    console.log('Button clicked!');
+  }
+}
+```
+
+### Component with Authentication:
+
+```typescript
+// src/app/protected/dashboard.component.ts
+import { Component } from '@angular/core';
+import { AuthGuard } from 'auth-client';
+import { TableComponent, CardComponent } from 'ui-essentials';
+import { StatisticsDisplayComponent } from 'ui-landing-pages';
+
+@Component({
+  selector: 'app-dashboard',
+  standalone: true,
+  imports: [TableComponent, CardComponent, StatisticsDisplayComponent],
+  template: `
+    <div class="dashboard">
+      <!-- Stats Cards -->
+      <div class="stats-grid">
+        <ui-statistics-display
+          [statistics]="stats"
+          variant="cards">
+        </ui-statistics-display>
+      </div>
+
+      <!-- Data Table -->
+      <ui-card>
+        <ui-enhanced-table
+          [data]="userData"
+          [columns]="tableColumns"
+          [searchable]="true"
+          [sortable]="true">
+        </ui-enhanced-table>
+      </ui-card>
+    </div>
+  `,
+  styles: [`
+    .dashboard {
+      padding: 1.5rem;
+    }
+    .stats-grid {
+      margin-bottom: 2rem;
+    }
+  `]
+})
+export class DashboardComponent {
+  stats = [
+    { label: 'Users', value: '1,234', change: '+12%' },
+    { label: 'Revenue', value: '$45,678', change: '+8%' },
+    { label: 'Orders', value: '892', change: '+15%' }
+  ];
+
+  userData = [
+    { id: 1, name: 'John Doe', email: 'john@example.com', status: 'active' },
+    { id: 2, name: 'Jane Smith', email: 'jane@example.com', status: 'inactive' }
+  ];
+
+  tableColumns = [
+    { key: 'id', label: 'ID' },
+    { key: 'name', label: 'Name' },
+    { key: 'email', label: 'Email' },
+    { key: 'status', label: 'Status' }
+  ];
+}
+```
+
+---
+
+## 🔄 Step 8: Library Management
+
+### Update a Single Library:
+```bash
+cd libs/ui-essentials
+git pull origin main
+npm run build
+cd ../..
+```
+
+### Update All Libraries:
+```bash
+git submodule update --remote
+./build-libs.sh  # Rebuild all libraries
+```
+
+### Lock Library to Specific Version:
+```bash
+cd libs/ui-essentials
+git checkout v1.2.0  # Specific tag
+cd ../..
+git add libs/ui-essentials
+git commit -m "Lock ui-essentials to v1.2.0"
+```
+
+### Remove Unused Library:
+```bash
+git submodule deinit libs/ui-backgrounds
+git rm libs/ui-backgrounds
+git commit -m "Remove ui-backgrounds library"
+```

+# SSuite Customization and Theming Guide
+
+## 🎨 Complete Guide to Styling and Overriding SSuite Libraries
+
+This guide shows you how to customize and theme your Angular project using the SSuite library ecosystem. Learn how to override colors, typography, components, and create your own design system on top of the foundation.
+
+---
+
+## 📋 Prerequisites
+
+Before customizing, ensure you have:
+- **SSuite libraries integrated** (follow `CONSUMER_INTEGRATION_GUIDE.md`)
+- **ui-design-system** added as a submodule (foundation library)
+- **Basic SCSS knowledge** for advanced customizations
+
+---
+
+## 🏗️ Customization Architecture
+
+SSuite uses a **layered architecture** for maximum flexibility:
+
+```
+Your Custom Theme
+       ↓
+  Semantic Tokens  ← Override here for colors, typography, spacing
+       ↓
+   Base Tokens    ← Override here for foundational values
+       ↓
+  Components      ← Override here for specific component styling
+```
+
+---
+
+## 🎯 Approach 1: CSS Custom Properties (Recommended)
+
+The easiest way to customize SSuite libraries using CSS variables.
+
+### 1. Create Your Theme File
+
+Create `src/styles/theme.scss`:
+
+```scss
+// ==========================================================================
+// YOUR CUSTOM THEME
+// ==========================================================================
+
+// Import design system first
+@use 'ui-design-system/src/styles' as ui;
+
+// ==========================================================================
+// 🎨 COLOR OVERRIDES
+// ==========================================================================
+
+:root {
+  // Primary Brand Colors
+  --color-primary: #6366f1;           // Your brand primary (indigo)
+  --color-secondary: #8b5cf6;         // Your brand secondary (purple)  
+  --color-tertiary: #10b981;          // Your accent color (emerald)
+  --color-error: #ef4444;             // Error/danger color (red)
+  
+  // Primary color variations
+  --color-primary-50: #eef2ff;
+  --color-primary-100: #e0e7ff;
+  --color-primary-500: #6366f1;       // Main primary
+  --color-primary-600: #4f46e5;
+  --color-primary-700: #4338ca;
+  --color-primary-900: #312e81;
+  
+  // Surface colors (backgrounds)
+  --color-surface: #ffffff;
+  --color-surface-variant: #f8fafc;
+  --color-surface-container: #f1f5f9;
+  --color-surface-dim: #e2e8f0;
+  
+  // Text colors on your custom colors
+  --color-on-primary: #ffffff;
+  --color-on-secondary: #ffffff;
+  --color-on-surface: #1e293b;
+  
+  // ==========================================================================
+  // ✍️ TYPOGRAPHY OVERRIDES  
+  // ==========================================================================
+  
+  // Font families (use your own fonts)
+  --font-family-sans: 'Inter', -apple-system, BlinkMacSystemFont, sans-serif;
+  --font-family-mono: 'JetBrains Mono', 'Fira Code', monospace;
+  --font-family-display: 'Playfair Display', Georgia, serif;
+  
+  // Font sizes
+  --font-size-xs: 0.75rem;    // 12px
+  --font-size-sm: 0.875rem;   // 14px  
+  --font-size-base: 1rem;     // 16px
+  --font-size-lg: 1.125rem;   // 18px
+  --font-size-xl: 1.25rem;    // 20px
+  --font-size-2xl: 1.5rem;    // 24px
+  --font-size-3xl: 1.875rem;  // 30px
+  --font-size-4xl: 2.25rem;   // 36px
+  
+  // ==========================================================================
+  // 📏 SPACING & SIZING OVERRIDES
+  // ==========================================================================
+  
+  // Border radius (adjust roundness)
+  --border-radius-sm: 0.25rem;   // 4px - subtle
+  --border-radius-base: 0.5rem;  // 8px - default
+  --border-radius-lg: 0.75rem;   // 12px - rounded
+  --border-radius-xl: 1rem;      // 16px - very rounded
+  
+  // Component-specific spacing
+  --spacing-button-padding-x: 1.5rem;  // Button horizontal padding
+  --spacing-button-padding-y: 0.75rem; // Button vertical padding
+  --spacing-card-padding: 1.5rem;      // Card interior padding
+  --spacing-section: 4rem;             // Section spacing
+}
+```
+
+### 2. Import Your Theme
+
+In `src/styles.scss`:
+
+```scss
+// Import your custom theme (this sets CSS variables)
+@import 'styles/theme';
+
+// Global styles using your theme
+body {
+  font-family: var(--font-family-sans);
+  background-color: var(--color-surface);
+  color: var(--color-on-surface);
+}
+
+// Apply theme to headings
+h1, h2, h3, h4, h5, h6 {
+  font-family: var(--font-family-display);
+  color: var(--color-primary);
+}
+
+// Custom link styling
+a {
+  color: var(--color-primary);
+  
+  &:hover {
+    color: var(--color-primary-600);
+  }
+}
+```
+
+---
+
+## 🎯 Approach 2: SCSS Variable Overrides (Advanced)
+
+For deeper customization, override SCSS variables before importing SSuite.
+
+### 1. Create Advanced Theme File
+
+Create `src/styles/advanced-theme.scss`:
+
+```scss
+// ==========================================================================
+// ADVANCED SCSS VARIABLE OVERRIDES
+// ==========================================================================
+
+// ==========================================================================
+// 🎨 COLOR VARIABLE OVERRIDES (before importing ui-design-system)
+// ==========================================================================
+
+// Override semantic colors
+$semantic-color-brand-primary: #7c3aed !default;        // Purple brand
+$semantic-color-brand-secondary: #059669 !default;      // Emerald secondary
+$semantic-color-brand-accent: #dc2626 !default;         // Red accent
+
+// Override feedback colors
+$semantic-color-success: #10b981 !default;              // Custom green
+$semantic-color-warning: #f59e0b !default;              // Custom amber
+$semantic-color-danger: #ef4444 !default;               // Custom red
+$semantic-color-info: #3b82f6 !default;                 // Custom blue
+
+// Override surface colors  
+$semantic-color-surface-primary: #ffffff !default;      // Pure white
+$semantic-color-surface-secondary: #f9fafb !default;    // Off-white
+$semantic-color-surface-elevated: #f3f4f6 !default;     // Light gray
+
+// ==========================================================================
+// ✍️ TYPOGRAPHY VARIABLE OVERRIDES
+// ==========================================================================
+
+// Font families
+$base-typography-font-family-sans: 'Inter', sans-serif !default;
+$base-typography-font-family-mono: 'JetBrains Mono', monospace !default;
+$base-typography-font-family-display: 'Playfair Display', serif !default;
+
+// Font sizes
+$base-typography-font-size-xs: 0.75rem !default;        // 12px
+$base-typography-font-size-sm: 0.875rem !default;       // 14px
+$base-typography-font-size-base: 1rem !default;         // 16px
+$base-typography-font-size-lg: 1.125rem !default;       // 18px
+$base-typography-font-size-xl: 1.25rem !default;        // 20px
+$base-typography-font-size-2xl: 1.5rem !default;        // 24px
+$base-typography-font-size-3xl: 1.875rem !default;      // 30px
+$base-typography-font-size-4xl: 2.25rem !default;       // 36px
+
+// Line heights
+$base-typography-line-height-tight: 1.25 !default;
+$base-typography-line-height-snug: 1.375 !default;
+$base-typography-line-height-normal: 1.5 !default;
+$base-typography-line-height-relaxed: 1.625 !default;
+
+// ==========================================================================
+// 📏 SPACING & LAYOUT OVERRIDES
+// ==========================================================================
+
+// Border radius
+$semantic-border-button-radius: 0.75rem !default;       // Rounded buttons
+$semantic-border-card-radius: 1rem !default;            // Very rounded cards
+$semantic-border-input-radius: 0.5rem !default;         // Moderate inputs
+
+// Spacing values
+$semantic-spacing-section-padding: 5rem !default;       // Generous sections
+$semantic-spacing-card-padding: 2rem !default;          // Spacious cards
+$semantic-spacing-interactive-button-padding-x: 2rem !default; // Wide buttons
+$semantic-spacing-interactive-button-padding-y: 0.875rem !default; // Tall buttons
+
+// NOW import ui-design-system (it will use your overridden variables)
+@use 'ui-design-system/src/styles' as ui;
+```
+
+### 2. Use Advanced Theme
+
+In `src/styles.scss`:
+
+```scss
+// Import your advanced theme
+@import 'styles/advanced-theme';
+
+// Global styles
+body {
+  font-family: ui.$base-typography-font-family-sans;
+  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
+  min-height: 100vh;
+}
+
+// Custom component styles
+.custom-hero {
+  background: linear-gradient(
+    45deg,
+    var(--color-primary),
+    var(--color-secondary)
+  );
+  color: white;
+  padding: var(--spacing-section);
+  border-radius: var(--border-radius-lg);
+}
+```
+
+---
+
+## 🎯 Approach 3: Component-Specific Overrides
+
+Target specific SSuite components for surgical customizations.
+
+### 1. Override Button Components
+
+Create `src/styles/component-overrides.scss`:
+
+```scss
+// ==========================================================================
+// COMPONENT-SPECIFIC OVERRIDES
+// ==========================================================================
+@use 'ui-design-system/src/styles' as ui;
+
+// ==========================================================================
+// 🔘 BUTTON OVERRIDES
+// ==========================================================================
+
+// Override all buttons
+ui-button, .ui-button {
+  // Custom button base
+  font-weight: 600;
+  text-transform: uppercase;
+  letter-spacing: 0.5px;
+  box-shadow: 0 4px 14px 0 rgba(0, 0, 0, 0.1);
+  transition: all 0.3s cubic-bezier(0.4, 0, 0.2, 1);
+  
+  // Custom hover effects
+  &:hover {
+    transform: translateY(-2px);
+    box-shadow: 0 8px 25px 0 rgba(0, 0, 0, 0.15);
+  }
+  
+  &:active {
+    transform: translateY(0);
+  }
+}
+
+// Primary button overrides
+ui-button[variant="primary"], .ui-button--primary {
+  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
+  border: none;
+  
+  &:hover {
+    background: linear-gradient(135deg, #5a6fd8 0%, #6a4190 100%);
+  }
+}
+
+// Secondary button overrides  
+ui-button[variant="secondary"], .ui-button--secondary {
+  background: transparent;
+  border: 2px solid var(--color-primary);
+  color: var(--color-primary);
+  
+  &:hover {
+    background: var(--color-primary);
+    color: var(--color-on-primary);
+  }
+}
+
+// Outline button overrides
+ui-button[variant="outline"], .ui-button--outline {
+  border: 2px solid currentColor;
+  background: rgba(255, 255, 255, 0.1);
+  backdrop-filter: blur(10px);
+}
+
+// ==========================================================================
+// 📋 FORM OVERRIDES
+// ==========================================================================
+
+// Input field overrides

+      transform: scale(1.05);
+    }
+  }
+}
+```
+
+### 2. Use Component Overrides
+
+In `src/styles.scss`:
+
+```scss
+// Import design system
+@use 'ui-design-system/src/styles' as ui;
+
+// Import your component overrides
+@import 'styles/component-overrides';
+```
+
+---
+
+## 🎯 Approach 4: Dark Mode Implementation
+
+Create a comprehensive dark mode theme.
+
+### 1. Create Dark Mode Theme
+
+Create `src/styles/dark-theme.scss`:
+
+```scss
+// ==========================================================================
+// DARK MODE THEME
+// ==========================================================================
+@use 'ui-design-system/src/styles' as ui;
+
+// Dark mode CSS variables
+[data-theme="dark"] {
+  // ==========================================================================
+  // 🌙 DARK MODE COLORS
+  // ==========================================================================
+  
+  // Primary colors (slightly brighter for dark mode)
+  --color-primary: #818cf8;           // Lighter indigo
+  --color-secondary: #a78bfa;         // Lighter purple
+  --color-tertiary: #34d399;          // Lighter emerald
+  
+  // Dark surfaces
+  --color-surface: #0f172a;           // Very dark blue
+  --color-surface-variant: #1e293b;   // Dark blue-gray
+  --color-surface-container: #334155; // Medium blue-gray
+  --color-surface-elevated: #475569;  // Light blue-gray
+  --color-surface-dim: #64748b;       // Muted blue-gray
+  
+  // Dark mode text colors
+  --color-on-surface: #f8fafc;        // Light text on dark
+  --color-on-primary: #1e1b4b;        // Dark text on light primary
+  --color-on-secondary: #2d1b69;      // Dark text on light secondary
+  
+  // Border colors for dark mode
+  --color-border: #374151;
+  --color-border-light: #4b5563;
+  
+  // ==========================================================================
+  // 🌙 DARK MODE COMPONENT OVERRIDES
+  // ==========================================================================
+  
+  // Card styling in dark mode
+  ui-card, .ui-card {
+    background: rgba(30, 41, 59, 0.8);
+    border-color: rgba(71, 85, 105, 0.3);
+    
+    &:hover {
+      background: rgba(51, 65, 85, 0.8);
+      border-color: rgba(71, 85, 105, 0.5);
+    }
+  }
+  
+  // Input styling in dark mode
+  ui-text-input input, .ui-text-input input {
+    background: rgba(30, 41, 59, 0.8);
+    border-color: var(--color-border);
+    color: var(--color-on-surface);
+    
+    &::placeholder {
+      color: #94a3b8;
+    }
+    
+    &:focus {
+      background: rgba(30, 41, 59, 1);
+      border-color: var(--color-primary);
+    }
+  }
+  
+  // Button adjustments for dark mode
+  ui-button[variant="secondary"], .ui-button--secondary {
+    border-color: var(--color-primary);
+    color: var(--color-primary);
+    
+    &:hover {
+      background: var(--color-primary);
+      color: var(--color-on-primary);
+    }
+  }
+}
+```
+
+### 2. Dark Mode Toggle Component
+
+Create a theme switcher:
+
+```typescript
+// src/app/components/theme-toggle.component.ts
+import { Component } from '@angular/core';
+import { ThemeSwitcherComponent } from 'ui-essentials';
+
+@Component({
+  selector: 'app-theme-toggle',
+  standalone: true,
+  imports: [ThemeSwitcherComponent],
+  template: `
+    <ui-theme-switcher
+      [themes]="themes"
+      (themeChange)="onThemeChange($event)">
+    </ui-theme-switcher>
+  `,
+  styles: [`
+    :host {
+      position: fixed;
+      top: 1rem;
+      right: 1rem;
+      z-index: 1000;
+    }
+  `]
+})
+export class ThemeToggleComponent {
+  themes = [
+    { id: 'light', name: 'Light', icon: '☀️' },
+    { id: 'dark', name: 'Dark', icon: '🌙' }
+  ];
+
+  onThemeChange(theme: string) {
+    document.documentElement.setAttribute('data-theme', theme);
+    localStorage.setItem('theme', theme);
+  }
+}
+```
+
+### 3. Initialize Theme
+
+In `src/app/app.component.ts`:
+
+```typescript
+import { Component, OnInit } from '@angular/core';
+import { ThemeToggleComponent } from './components/theme-toggle.component';
+
+@Component({
+  selector: 'app-root',
+  standalone: true,
+  imports: [ThemeToggleComponent],
+  template: `
+    <div class="app">
+      <app-theme-toggle></app-theme-toggle>
+      <!-- Your app content -->
+    </div>
+  `
+})
+export class AppComponent implements OnInit {
+  ngOnInit() {
+    // Initialize theme from localStorage
+    const savedTheme = localStorage.getItem('theme') || 'light';
+    document.documentElement.setAttribute('data-theme', savedTheme);
+  }
+}
+```
+
+---
+
+## 🎯 Approach 5: Custom Brand Components
+
+Create your own branded components on top of SSuite.
+
+### 1. Custom Branded Button
+
+Create `src/app/components/brand-button.component.ts`:
+
+```typescript
+import { Component, Input } from '@angular/core';

+      overflow: hidden;
+      
+      // Gradient effect
+      &.gradient {

+        }
+        
+        &:hover:before {
+          left: 100%;
+        }
+      }
+      
+      // Glass morphism effect

+})
+export class BrandButtonComponent {
+  @Input() variant: 'primary' | 'secondary' | 'outline' = 'primary';
+  @Input() size: 'sm' | 'md' | 'lg' = 'md';
+  @Input() disabled = false;
+  @Input() gradient = false;
+  @Input() glass = false;
+}
+```
+
+### 2. Custom Hero Section
+
+Create `src/app/components/brand-hero.component.ts`:
+
+```typescript
+import { Component, Input } from '@angular/core';
+import { HeroSectionComponent } from 'ui-landing-pages';

+## 🎯 Real-World Examples
+
+### Example 1: E-commerce Theme
+
+```scss
+// src/styles/ecommerce-theme.scss
+:root {
+  // E-commerce focused colors
+  --color-primary: #059669;        // Forest green (trust)

+    transform: translateY(-4px);
+    box-shadow: 0 12px 24px rgba(0,0,0,0.15);
+  }
+}
+```
+
+### Example 2: SaaS Platform Theme
+
+```scss
+// src/styles/saas-theme.scss
+:root {
+  // SaaS professional colors
+  --color-primary: #3b82f6;        // Professional blue
+  --color-secondary: #6366f1;      // Indigo accent

+  }
+  
+  .main-content {
+    padding: var(--spacing-dashboard-padding);
+  }
+}
+```
+
+---
+
+## 📚 Advanced Customization Tips
+
+### 1. Use CSS Custom Properties for Runtime Changes
+
+```typescript
+// Dynamically change theme colors
+export class ThemeService {
+  setThemeColor(property: string, value: string) {
+    document.documentElement.style.setProperty(`--${property}`, value);
+  }
+  
+  // Example: User customization
+  applyUserTheme(userTheme: UserTheme) {
+    this.setThemeColor('color-primary', userTheme.primaryColor);
+    this.setThemeColor('font-family-sans', userTheme.fontFamily);
+    this.setThemeColor('border-radius-base', userTheme.borderRadius);
+  }
+}
+```
+
+### 2. Component-Level CSS Custom Properties
+
+```scss
+ui-button {
+  // Component-specific custom properties
+  --btn-padding-x: 2rem;
+  --btn-font-weight: 700;
+  --btn-border-radius: 0.75rem;
+}
+
+// Modify specific button instances
+.hero-button {
+  --btn-padding-x: 3rem;
+  --btn-font-size: 1.25rem;
+}
+```
+
+### 3. Responsive Theme Adjustments
+
+```scss
+:root {
+  --font-size-hero: 2.5rem;
+  --spacing-section: 3rem;
+}
+
+@media (min-width: 768px) {
+  :root {
+    --font-size-hero: 4rem;
+    --spacing-section: 5rem;
+  }
+}
+```
+
+---
+
+## ✅ Best Practices
+
+### 1. **Layer Your Customizations**
+- Start with CSS custom properties for quick changes
+- Use SCSS variables for deeper customizations
+- Create component overrides for specific needs
+
+### 2. **Maintain Consistency**
+- Define a clear color palette
+- Use consistent spacing scales
+- Maintain typography hierarchy
+
+### 3. **Test Across Components**
+- Ensure your theme works across all SSuite components
+- Test in both light and dark modes
+- Verify accessibility (contrast ratios)
+
+### 4. **Performance Considerations**
+- Use CSS custom properties for dynamic changes
+- Avoid excessive nesting in component overrides
+- Minimize redundant style declarations
+
+### 5. **Documentation**
+- Document your theme variables
+- Create a style guide for your team
+- Maintain examples of themed components
+
+---
+
+## 🚀 Quick Start Templates
+
+### Minimal Customization (5 minutes)
+```scss
+// src/styles.scss
+@use 'ui-design-system/src/styles' as ui;
+
+:root {
+  --color-primary: #your-brand-color;
+  --font-family-sans: 'Your Font', sans-serif;
+}
+```
+
+### Medium Customization (30 minutes)
+- Use Approach 1 (CSS Custom Properties)
+- Add dark mode support
+- Create 2-3 component overrides
+
+### Full Customization (2+ hours)  
+- Use Approach 2 (SCSS Variable Overrides)
+- Implement comprehensive dark mode
+- Create branded components
+- Add responsive theme adjustments

+# Git Submodule Integration Guide
+
+## 🎯 Implementation Complete!
+
+All 12 libraries have been successfully extracted into individual repositories ready for Git submodule distribution.
+
+## 📦 Extracted Libraries
+
+### Foundation Libraries
+1. **ui-design-system** - SCSS design system with tokens and fonts
+2. **shared-utils** - Common utilities and shared services  
+3. **ui-data-utils** - Data manipulation utilities
+
+### Standalone Libraries
+4. **ui-animations** - CSS animation utilities
+5. **ui-accessibility** - Accessibility features and WCAG compliance
+6. **ui-backgrounds** - Background generation utilities
+7. **ui-font-manager** - Font management and theming
+8. **hcl-studio** - HCL color management system
+9. **auth-client** - Authentication with guards and interceptors
+
+### Component Libraries
+10. **ui-code-display** - Code syntax highlighting (requires prismjs)
+11. **ui-essentials** - Essential UI components (buttons, forms, etc.)
+12. **ui-landing-pages** - Landing page components and templates
+
+## 🚀 Consumer Integration
+
+### Step 1: Add Libraries as Submodules
+
+**IMPORTANT**: Always add `ui-design-system` first, as other libraries depend on it.
+
+```bash
+# Navigate to your project
+cd your-angular-project
+
+# REQUIRED: Add ui-design-system first (foundation dependency)
+git submodule add https://github.com/yourorg/ui-design-system.git libs/ui-design-system
+
+# Add other libraries you need
+git submodule add https://github.com/yourorg/ui-essentials.git libs/ui-essentials
+git submodule add https://github.com/yourorg/auth-client.git libs/auth-client
+
+# Initialize and update submodules
+git submodule update --init --recursive
+```
+
+### Step 2: Install Dependencies
+
+```bash
+# Build ui-design-system first (required by other libraries)
+cd libs/ui-design-system && npm install && npm run build
+cd ../..
+
+# Build other libraries (they now reference ui-design-system via standardized paths)
+cd libs/ui-essentials && npm install && npm run build  
+cd ../auth-client && npm install && npm run build
+cd ../..
+```
+
+### Step 3: Update tsconfig.json
+
+```json
+{
+  "compilerOptions": {
+    "paths": {
+      "ui-design-system": ["./libs/ui-design-system/dist"],
+      "ui-design-system/*": ["./libs/ui-design-system/dist/*", "./libs/ui-design-system/src/*"],
+      "ui-essentials": ["./libs/ui-essentials/dist"],
+      "ui-essentials/*": ["./libs/ui-essentials/dist/*"],
+      "auth-client": ["./libs/auth-client/dist"],
+      "auth-client/*": ["./libs/auth-client/dist/*"]
+    }
+  }
+}
+```
+
+**Note**: The `ui-design-system/*` path includes both `dist/*` and `src/*` to support SCSS imports from source files.
+
+### Step 4: Use in Your Application
+
+```typescript
+// Import from any library
+import { ButtonComponent } from 'ui-essentials';
+import { AuthService } from 'auth-client';
+import { UiDesignSystemService } from 'ui-design-system';
+
+// Import styles
+// In your styles.scss
+@use 'ui-design-system/src/styles' as ui;
+```
+
+## 🔄 Library Updates
+
+### Update a Single Library
+```bash
+cd libs/ui-essentials
+git pull origin main
+npm run build
+cd ../..
+```
+
+### Update All Libraries
+```bash
+git submodule update --remote
+# Then rebuild each library as needed
+```
+
+### Lock to Specific Versions
+```bash
+cd libs/ui-essentials
+git checkout v1.2.0  # Specific tag/version
+cd ../..
+git add libs/ui-essentials
+git commit -m "Lock ui-essentials to v1.2.0"
+```
+

+
+## 🛠 Development Workflow
+
+### For Library Consumers
+
+1. **Add library**: `git submodule add <repo-url> libs/<name>`
+2. **Build library**: `cd libs/<name> && npm run build`
+3. **Use library**: Import from library name in TypeScript
+4. **Update library**: `cd libs/<name> && git pull`
+
+### For Library Development
+
+Each library is now an independent project:
+- Separate Git repository
+- Independent versioning
+- Own CI/CD pipeline
+- Individual releases
+
+## 🔧 Standardized Import System
+
+All libraries now use **standardized paths** instead of relative paths for ui-design-system imports:
+
+**Before (Problematic)**:
+```scss
+@use "../../../../../../ui-design-system/src/styles/semantic/index" as *;
+@use '../../../../../ui-design-system/src/styles/semantic' as *;
+```
+
+**After (Standardized)**:
+```scss
+@use 'ui-design-system/src/styles/semantic/index' as *;
+@use 'ui-design-system/src/styles/semantic' as *;
+```
+
+### Benefits:
+- ✅ **Path independence**: Libraries work regardless of file system structure
+- ✅ **Clean imports**: No more complex relative paths (`../../../..`)
+- ✅ **True portability**: Each library is self-contained
+- ✅ **Consumer flexibility**: Add ui-design-system at any submodule structure
+
+## 🎯 Benefits Achieved
+
+### ✅ For LLM Analysis
+- **Complexity reduction**: 12 focused repositories vs 1 monorepo
+- **Clean APIs**: Each library has optimized public-api.ts
+- **Focused context**: Analyze one library at a time
+- **Clear boundaries**: Well-defined library responsibilities
+- **Standardized imports**: 193+ import statements now use clean, consistent paths
+
+### ✅ For Development
+- **Selective inclusion**: Only add libraries you need
+- **Independent versioning**: Lock libraries to specific versions
+- **Reusable across projects**: Same libraries in multiple projects
+- **Professional distribution**: Industry-standard submodule approach
+- **Dependency management**: Clear ui-design-system foundation requirement
+
+### ✅ for Maintenance
+- **Isolated changes**: Updates don't affect other libraries
+- **Clear ownership**: Each library can have dedicated maintainers
+- **Better testing**: Test libraries in isolation
+- **Release management**: Independent release cycles
+- **Import consistency**: All SCSS imports follow the same standardized pattern
+
+## 🔧 Next Steps
+
+1. **Create Git repositories** for each extracted library
+2. **Initialize with git init** in each library folder
+3. **Push to your Git hosting** (GitHub, GitLab, etc.)
+4. **Update URLs** in integration examples above
+5. **Create initial releases/tags** for versioning
+
+## 📊 Before vs After
+
+**Before (Monorepo)**:
+- 1 repository with 12 libraries
+- ~50,000+ files for LLM to parse
+- Complex interdependencies
+- All-or-nothing updates
+
+**After (Submodules)**:
+- 12 focused repositories  
+- ~500-2000 files per library for LLM
+- Clean, documented APIs
+- Selective library inclusion
+- Independent evolution
+
+Your library ecosystem is now ready for professional distribution and optimal LLM analysis!

+# UI Landing Pages Library Implementation Plan
+
+## Executive Summary
+
+This document outlines the implementation strategy for creating a comprehensive `ui-landing-pages` library within the SSuite Angular workspace. The library will provide production-ready components specifically designed for building modern websites and landing pages, leveraging Angular 19 features and integrating seamlessly with existing libraries: `ui-design-system`, `ui-essentials`, `ui-animations`, `ui-backgrounds`, `ui-code-display`, and `shared-utils`.
+
+## Technical Foundation
+
+### Angular 19 Requirements
+- **Standalone Components**: All components will be standalone (no NgModules)
+- **Control Flow Syntax**: Use `@if`, `@for`, `@switch` (not `*ngIf`, `*ngFor`)
+- **Signals**: Prefer signals over observables for state management
+- **Inject Function**: Use `inject()` function over constructor injection
+- **OnPush Change Detection**: Default for all components
+- **@defer**: Implement lazy loading where appropriate
+
+### Design System Integration
+
+#### Token Import Path
+```scss
+// Correct import path for semantic tokens
+@use '../../../../../ui-design-system/src/styles/semantic/index' as *;
+```
+
+#### Typography Strategy
+The design system provides comprehensive typography tokens as maps and single values:
+- **Headings**: Use `$semantic-typography-heading-h1` through `h5` (maps)
+- **Body Text**: Use `$semantic-typography-body-large/medium/small` (maps)
+- **Component Text**: Use `$semantic-typography-button-*` variants (maps)
+
+#### Component Architecture Principles
+- **NO hardcoded values**: All styling must use semantic tokens
+- **BEM methodology**: Consistent class naming convention
+- **Component composition**: Leverage existing `ui-essentials` components
+- **Accessibility first**: WCAG 2.1 AA compliance required

+- **Keyboard Navigation**: Full keyboard support with visible focus
+- **Screen Readers**: Meaningful alt text and announcements
+- **Color Contrast**: Minimum 4.5:1 ratio for text
+
+### Testing Strategy
+```typescript
+// Example test structure
+describe('HeroSectionComponent', () => {
+  let component: HeroSectionComponent;
+  let fixture: ComponentFixture<HeroSectionComponent>;
+
+  beforeEach(async () => {
+    await TestBed.configureTestingModule({
+      imports: [HeroSectionComponent]
+    }).compileComponents();
+
+    fixture = TestBed.createComponent(HeroSectionComponent);
+    component = fixture.componentInstance;
+  });
+
+  it('should apply correct alignment class', () => {
+    component.configuration = { 
+      title: 'Test', 
+      alignment: 'left' 
+    };
+    fixture.detectChanges();
+    
+    const element = fixture.nativeElement.querySelector('.ui-lp-hero');
+    expect(element).toHaveClass('ui-lp-hero--left');
+  });
+
+  it('should emit CTA click events', () => {
+    const spy = spyOn(component.ctaClicked, 'emit');
+    const mockCTA = { 
+      text: 'Click', 
+      variant: 'primary' as const, 
+      action: () => {} 
+    };
+    
+    component.handleCTAClick(mockCTA);
+    expect(spy).toHaveBeenCalledWith(mockCTA);
+  });
+});
+```
+
+### Demo Application Integration
+
+Each component will have a comprehensive demo in `demo-ui-essentials`:
+
+```typescript
+// demos.routes.ts addition
+@case ("landing-hero") {
+  <ui-lp-hero-demo></ui-lp-hero-demo>
+}
+@case ("landing-features") {
+  <ui-lp-features-demo></ui-lp-features-demo>
+}
+@case ("landing-pricing") {
+  <ui-lp-pricing-demo></ui-lp-pricing-demo>
+}
+// ... etc
+```
+
+### Build Configuration
+
+```json
