feat: iframe-based PagedJS preview with reactive CSS editor
- Isolate PagedJS in iframe to avoid DOM/CSS conflicts - Add EditorPanel for global CSS controls - Add StylesheetViewer with highlight.js syntax highlighting - Add ElementPopup for element-specific CSS editing - CSS modifications update preview reactively - Support px/rem/em units 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
