```

## Next Steps for Deployment

1. **Icons**: Replace placeholder icons with proper Binect-branded icons (SVG source recommended)
2. **API Endpoint**: Verify Binect API endpoint URL and adjust if needed
3. **Testing**: Manual testing in Chrome browser
4. **Chrome Web Store**: Prepare for publication
   - Create developer account
   - Prepare screenshots
   - Write store description
   - Submit for review

## Known Limitations (By Design)

1. **PDF Detection**: Blob URLs and complex JavaScript viewers may not be detectable (documented in PRD)
2. **Browser Support**: Chrome only in v1 (Manifest V3)
3. **Encryption**: Not hardware-backed (acceptable for v1, documented in ADR-001)
