## Technical Implementation

### Markdown to HTML Conversion:

- ✅ Full control over output HTML
- ✅ Optimized for Supervertaler report structure
- ✅ Predictable, consistent output

**Conversion Process**:
1. Parse Markdown line-by-line
2. Detect structural elements (headers, lists, code)
3. Convert to semantic HTML tags
4. Apply inline formatting (bold, code)
5. Wrap in styled HTML document
6. Write to `.html` file

### HTML Template Structure:
```html
<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Session Report</title>
    <style>/* Embedded CSS */</style>
  </head>
  <body>
    <div class="container">
      <!-- Converted Markdown content -->
    </div>
  </body>
</html>
```

**Advantages of Embedded CSS**:
- ✅ Single self-contained file
- ✅ No external dependencies
- ✅ Works offline
- ✅ Easy to share/move
