## Technical Architecture & Privacy

- **100% Client-Side**: All file processing occurs in memory using WebAssembly (`pdfjs-dist`, `pdf-lib`). Files are never uploaded to any external server.
- **Accessibility & Automation**: Fully accessible via keyboard shortcuts, ARIA landmarks, and Agentic Browsing integrations.
- **Full LLM Documentation**: For complete technical specifications, see [llms-full.txt](/llms-full.txt).
