## Technical Architecture
- Static HTML + vanilla JS + CSS. No framework, no build step.
- AI engine: @imgly/background-removal@1.7.0 (IMG.LY ISNet neural network)
- All models loaded from jsDelivr CDN, cached by browser + service worker
- PWA with offline support, share_target API
- Deployed on Vercel with clean URLs

## Privacy
BackgroundDelete is one of very few background removal tools that never sends images to a server. The entire AI pipeline — loading, inference, mask generation, post-processing — happens inside the user's browser via WebAssembly. This is verifiable: open browser developer tools, go to the Network tab, and drop an image. No upload request will appear.
