+# Code Cleanup Summary
+
+## Artifacts Removed from Architecture Pivot
+
+### 🗑️ **Obsolete Assets Removed**
+- `insertr-cli/assets/editor/insertr-editor.js` - Legacy inline editor script
+- `insertr-cli/assets/editor/` directory - No longer needed
+- Unused `marked` npm dependency from root package.json
+
+### 🧹 **Root Package.json Cleanup**
+**Before:**
+```json
+{
+  "description": "Edit-in-place CMS for client websites - simple integration with class-based content editing",
+  "main": "demo-site/insertr/insertr.js",
+  "keywords": ["cms", "edit-in-place", "inline-editing", "client-websites", "go", "htmx", "alpine"],
+  "dependencies": {
+    "marked": "^16.2.1"
+  }
+}
+```
+
+**After:**
+```json
+{
+  "description": "The Tailwind of CMS - Zero-configuration content editing for any static site",
+  "main": "lib/dist/insertr.js", 
+  "keywords": ["cms", "headless-cms", "static-site-generator", "build-time-enhancement", "zero-config", "go", "javascript"],
+  "dependencies": {}
+}
+```
+
+### ✅ **Legacy Code Preserved (Intentionally)**
+- `demo-site/archive/` - Contains original prototype for reference
+- `scripts/dev.js` - Still useful for testing original prototype
+- Legacy npm scripts (`dev:*`) - Kept for prototype development
+- `demo-site/README.md` - Accurately describes prototype functionality
+
+### 🔧 **Enhanced .gitignore**
+Added new build artifacts:
+```gitignore
+# Build outputs  
+lib/dist/              # Library build output
+insertr-cli/insertr    # CLI executable
+insertr-cli/tmp/       # Air temporary files
+insertr-cli/build-errors.log  # Air error logs
+```
+
+### 🎯 **What Was NOT Removed**
+- **Archive directory**: `demo-site/archive/` kept for reference
+- **Development scripts**: Legacy scripts still work for prototype testing
+- **Documentation references**: Accurate historical context preserved
+- **Go embed assets**: `insertr-cli/pkg/content/assets/` must stay for embedding
+
+## Validation
+
+### ✅ **Build System Verified**
+```bash
+npm run build           # ✅ Works  
+cd insertr-cli && air   # ✅ Hot reload works
+./insertr enhance       # ✅ CLI works with embedded library
+```
+
+### ✅ **Architecture Clean**
+- No dead code or unused imports in Go
+- No obsolete script references  
+- Clean dependency tree (1 package removed)
+- Updated project metadata reflects current architecture
+
+### 🎯 **Result**
+The codebase now cleanly separates:
+1. **Current Architecture**: `lib/` + `insertr-cli/` with proper embedding
+2. **Legacy Prototype**: `demo-site/archive/` for reference
+3. **Test Content**: `demo-site/` HTML files for enhancement testing
+
+No functionality was lost, and the transition from prototype to production architecture is complete.

 ## Quick Start
 
+### Full-Stack Development (Recommended)
 1. **Install dependencies**:
    ```bash
-   npm install
+   npm install                    # Root project dependencies
+   cd lib && npm install         # Library dependencies
    ```
 
-2. **Start development server**:
+2. **Start hot reload development**:
    ```bash
-   npm run dev
+   cd insertr-cli && air         # Starts server with library hot reload
    ```
-   This will start live-server on http://localhost:3000 and automatically open the demo site.
+   - Watches both Go CLI changes AND JavaScript library changes
+   - Automatically rebuilds library → CLI → serves enhanced content
+   - Visit http://localhost:3000 to see results
 
-3. **Alternative commands**:
-   ```bash
-   npm run dev:about    # Open about page directly
-   npm run serve        # Alias for npm run dev
-   ```
+### Library-Only Development
+```bash
+cd lib && npm run watch         # Just develop the JavaScript library
+```
+
+### Legacy Frontend Development
+```bash
+npm run dev                     # Legacy live-server (demo-site only)
+```
 
 ## Development Workflow
 
-### Frontend Development (Current Phase)
+### Hot Reload Development (Current Phase)
+
+**🔥 NEW**: Full-stack hot reload with Air integration!
+
+- **Library Source**: `lib/src/` - Independent JavaScript library
+- **CLI Integration**: `insertr-cli/` - Go CLI with embedded library
+- **Demo Site**: `demo-site/` - Test website for enhancement
+- **Automatic Rebuilds**: Changes to JS library trigger full rebuild cycle
+
+#### How Hot Reload Works:
+1. Edit JavaScript in `lib/src/` 
+2. Air detects changes → Rebuilds library → Copies to CLI → Rebuilds CLI
+3. Enhanced development server serves updated content
+4. Manual browser refresh shows changes
+
+### Legacy Frontend Development
 
 - **Demo Site**: `demo-site/` contains the prototype website
-- **Core Library**: `demo-site/insertr/insertr.js` - the main Insertr library
-- **Styling**: `demo-site/insertr/insertr.css` - edit interface styles
+- **Core Library**: `demo-site/insertr/insertr.js` - the old prototype library  
 - **Mock API**: `demo-site/mock-api/content.json` - sample backend data structure

 ### Making Changes
 
+#### Modern Development (lib/ + insertr-cli/)
+- **Library Changes**: Edit `lib/src/**/*.js` → Air automatically rebuilds everything
+- **CLI Changes**: Edit Go files in `insertr-cli/` → Air rebuilds and restarts server  
+- **Demo Content**: Edit `demo-site/*.html` → Air serves enhanced versions
+- **Hot Reload**: Changes trigger full rebuild cycle (library → CLI → enhanced content)
+
+#### Legacy Development (demo-site/)
 - **Live Reload**: The server automatically refreshes when you save changes
-- **JavaScript**: Edit `demo-site/insertr/insertr.js` to modify core functionality
-- **Styling**: Edit `demo-site/insertr/insertr.css` for UI changes
+- **JavaScript**: Edit `demo-site/insertr/insertr.js` for prototype functionality
 - **Content**: Edit HTML files to test different content structures

+# Insertr Library Architecture
+
+## Overview
+
+Insertr now uses a proper separation between the JavaScript library and Go CLI, following the "Tailwind of CMS" philosophy where the library can be developed independently and embedded into the CLI at build time.
+
+## Project Structure
+
+```

+│   └── insertr                  # Built CLI executable
+└── scripts/
+    └── build.js                 # Integrated build script
+```
+
+## Build Process
+
+### 1. Library Development (`lib/`)
+```bash
+cd lib
+npm install
+npm run build    # Creates dist/insertr.js and dist/insertr.min.js
+npm run watch    # Development mode with file watching
+```
+
+### 2. CLI Integration (`insertr-cli/`)
+The CLI uses Go's `//go:embed` directive to embed the built library:
+
+```go
+//go:embed assets/insertr.min.js
+var libraryMinJS string
+
+//go:embed assets/insertr.js  
+var libraryJS string
+```
+
+### 3. Integrated Build (Root)
+```bash
+npm run build    # Builds both library AND CLI with embedded assets
+```
+
+This script:
+1. Builds the JavaScript library (`lib/dist/`)
+2. Copies built assets to CLI (`insertr-cli/pkg/content/assets/`)
+3. Builds Go CLI with embedded library
+
+## Library Features
+
+### Core Functionality (`src/core/insertr.js`)
+- Element discovery: `findEnhancedElements()`
+- Metadata extraction: `getElementMetadata()`
+- Element management: `getAllElements()`
+
+### Visual Editor (`src/core/editor.js`)
+- Hover effects and visual indicators
+- Click-to-edit functionality  
+- Content update handling
+- Dynamic style injection
+
+### API Client (`src/core/api-client.js`)
+- RESTful content API communication
+- CRUD operations for content
+- Error handling and fallbacks
+
+## CLI Integration
+
+### Asset Embedding (`pkg/content/library.go`)
+```go
+func GetLibraryScript(minified bool) string {
+    if minified {
+        return libraryMinJS  // Production: smaller file size
+    }
+    return libraryJS         // Development: readable code
+}
+```
+
+### HTML Injection (`pkg/content/injector.go`)
+```go
+func (i *Injector) InjectEditorAssets(doc *html.Node, isDevelopment bool, libraryScript string) {
+    // Injects the embedded library as inline <script> tag
+}
+```
+
+## Development Workflow
+
+### Library Development
+```bash
+cd lib
+npm run watch    # Auto-rebuild on changes
+```
+
+### CLI Development  
+```bash
+cd insertr-cli
+go build -o insertr
+./insertr enhance ../demo-site/
+```
+
+### Full Integration Testing
+```bash
+npm run build    # Builds library + CLI
+cd insertr-cli && ./insertr enhance ../demo-site/
+```
+
+## Benefits
+
+1. **Independent Development**: Library can be developed and tested separately
+2. **Version Control**: CLI embeds specific library version at build time
+3. **Zero Dependencies**: Enhanced HTML contains everything needed to run
+4. **CDN Ready**: Library can be served from CDN in production
+5. **Development Friendly**: Unminified version for debugging
+
+## Future Enhancements
+
+- **CDN Integration**: Support for `<script src="https://cdn.insertr.dev/v1.0.0/insertr.min.js">`
+- **Library Hot Reload**: Auto-rebuild CLI when library changes
+- **Version Sync**: Automated version bumping across library and CLI
+- **Production Optimization**: Tree-shaking and custom builds

+# Insertr Library Feature Parity TODO
+
+## Overview
+Bring the current library (`lib/`) up to feature parity with the archived prototype (`demo-site/archive/insertr-old/`). The prototype has significantly more features and professional polish than our current basic library.
+
+## Critical Feature Gaps Identified
+
+### Current Library Status: Basic Proof-of-Concept
+- ❌ Simple prompt() editing only
+- ❌ No authentication or state management  
+- ❌ No form system or validation
+- ❌ No content persistence
+- ❌ Text-only editing (no markdown, links)
+- ❌ Basic hover effects only
+
+### Prototype Status: Production-Ready
+- ✅ Professional modal editing system
+- ✅ Full authentication & edit mode states
+- ✅ Sophisticated form renderer with validation
+- ✅ LocalStorage persistence
+- ✅ Multiple content types (text/markdown/link)
+- ✅ Mobile-responsive design
+
+## Implementation Plan
+
+### 🔴 Phase 1: Critical Foundation (IMMEDIATE)
+
+#### 1.1 Authentication System
+- [ ] Add state management for authentication and edit mode
+- [ ] Implement body class management (`insertr-authenticated`, `insertr-edit-mode`)
+- [ ] Create authentication controls (login/logout toggle)
+- [ ] Add edit mode toggle (separate from authentication)
+
+#### 1.2 Professional Edit Forms ⭐ **HIGH IMPACT**
+- [ ] Replace prompt() with professional modal overlays
+- [ ] Create dynamic form renderer based on content type
+- [ ] Implement smart form positioning relative to elements
+- [ ] Add mobile-responsive form layouts
+
+#### 1.3 Content Type Support
+- [ ] Text fields with length validation
+- [ ] Textarea fields for paragraphs
+- [ ] Link fields (URL + text) with validation
+- [ ] Markdown fields with live preview
+
+#### 1.4 Data Persistence
+- [ ] Implement LocalStorage-based content persistence
+- [ ] Create centralized content management system
+- [ ] Add content caching and invalidation
+
+### 🟡 Phase 2: Enhanced UX (IMPORTANT)
+
+#### 2.1 Visual Polish
+- [ ] Add positioned edit buttons on element hover
+- [ ] Implement professional hover effects and transitions
+- [ ] Create loading states for save operations
+- [ ] Add success/error toast notifications
+
+#### 2.2 Validation System
+- [ ] Input validation (length, required fields, format)
+- [ ] URL validation for link fields
+- [ ] Markdown syntax validation and warnings
+- [ ] XSS protection and content sanitization
+
+#### 2.3 Configuration System
+- [ ] Auto-detect field types from HTML elements (H1-H6, P, A, etc.)
+- [ ] CSS class-based enhancement (`.lead`, `.btn-primary`, etc.)
+- [ ] Developer-extensible field type system
+- [ ] Configurable validation rules per field type
+
+### 🟢 Phase 3: Advanced Features (NICE-TO-HAVE)
+
+#### 3.1 Markdown System
+- [ ] Port full markdown processing system from prototype
+- [ ] Real-time markdown preview in edit forms
+- [ ] DOMPurify integration for security
+- [ ] Markdown toolbar (bold, italic, links)
+
+#### 3.2 Mobile Optimization
+- [ ] Touch-friendly edit interactions
+- [ ] Full-screen mobile edit experience
+- [ ] Adaptive modal sizing and positioning
+- [ ] Touch-optimized hover states
+
+## Key Files to Port/Adapt
+
+### From Prototype (`demo-site/archive/insertr-old/`)
+- `config.js` → `lib/src/core/config.js` (field type detection)
+- `form-renderer.js` → `lib/src/ui/form-renderer.js` (modal forms)
+- `validation.js` → `lib/src/core/validation.js` (input validation)
+- `content-manager.js` → `lib/src/core/content-manager.js` (persistence)
+- `markdown-processor.js` → `lib/src/core/markdown.js` (markdown support)
+- `insertr.css` → `lib/src/styles/` (professional styling)
+
+### Architecture Adaptations Needed
+- **Build-Time Integration**: Ensure features work with CLI-enhanced HTML
+- **Hot Reload Compatibility**: Maintain development experience
+- **Library Independence**: Keep self-contained for CDN usage
+- **Modern ES6+ Modules**: Update from class-based to module-based architecture
+
+## Success Criteria
+
+After Phase 1 & 2 completion:
+- ✅ Professional editing experience matching prototype quality
+- ✅ All critical content types supported (text/markdown/link)
+- ✅ Authentication and state management working
+- ✅ Persistent content storage with LocalStorage
+- ✅ Mobile-responsive editing interface
+- ✅ Input validation and XSS protection
+
+## Next Steps
+
+1. **Start with Phase 1.2** (Professional Edit Forms) - highest user impact
+2. **Port form-renderer.js** first - creates immediate professional feel
+3. **Test integration** with CLI enhancement pipeline
+4. **Maintain hot reload** functionality during development
+
+## Architecture Decision
+
+Keep the current library + CLI architecture while porting prototype features:
+- Library remains independent and CDN-ready
+- CLI continues build-time enhancement approach
+- Hot reload development experience preserved
+- "Tailwind of CMS" philosophy maintained
+
+---
+
+*This TODO represents bringing a basic proof-of-concept up to production-ready feature parity with the original prototype.*
