tegwick b84770e2d3 feat: add standalone JavaScript proof of concept
Created examples/standalone.html demonstrating testdrive-jsui as a pure
JavaScript library that works without any backend.

Features:
- Opens directly in browser (file:// works)
- Markdown rendering using marked.js from CDN
- Save/load content to browser localStorage
- Download markdown files
- No Python/Ruby/Java required

Validates JavaScript-first architecture:
- All rendering happens in browser
- Backend adapters are truly optional
- Zero coupling to any specific backend

Added examples/README.md:
- Usage instructions (just open in browser!)
- Architecture validation notes
- Next steps for full implementation

This proves the concept that testdrive-jsui can be a standalone
JavaScript library with language adapters being optional integration
helpers, not core functionality providers.

## What is This?
This is a **standalone demonstration** of TestDrive-JSUI working as a pure JavaScript library. Everything you see is rendered in your browser using JavaScript - no server required!
### Key Features
- ✅ **Pure JavaScript**: Runs entirely in the browser
- ✅ **Markdown Rendering**: Uses marked.js for parsing
- ✅ **Standalone**: No backend, no build tools needed
- ✅ **Portable**: Open this file anywhere - it just works!
- ✅ **LocalStorage**: Save and load your content locally
## How It Works
1. **Markdown Input**: Content is stored as markdown text
2. **marked.js**: Parses markdown to HTML
3. **TestDrive-JSUI**: Renders and manages the UI
4. **Browser**: Displays everything natively
## Try It Out!
You can:
- Edit this content (coming soon in full version)
- Save to browser localStorage
- Download as a .md file
- Load previously saved content
## Code Example
\`\`\`javascript
// Initialize the editor
const editor = {
markdown: '# Hello World',
render: function() {
const html = marked.parse(this.markdown);
document.getElementById('editor-container').innerHTML = html;
}
};
\`\`\`
## Architecture Benefits
### JavaScript Library
The core functionality is pure JavaScript:
- Markdown parsing
- UI rendering
- Section management
- Event handling
### Optional Adapters
Language-specific adapters (Python, Ruby, Java) just help with:
- Serving assets
- Backend integration
- Testing infrastructure
But they're **not required** for core functionality!
## Next Steps
This proof of concept demonstrates that TestDrive-JSUI can work as a standalone JavaScript library. The full implementation will include:
1. **Edit Mode**: Interactive editing with controls
2. **Section Management**: Edit sections independently
3. **Auto-save**: Automatic localStorage saves
4. **Themes**: Multiple visual themes
5. **Plugins**: Extension system
---
**Status**: Proof of Concept ✅
**Architecture**: JavaScript-First ✅
**Backend Required**: No ❌
