Overlay runtime that turns any responsive web app into a polished widget or extension.
Widget Shell provides a production‑grade runtime that lets developers embed any responsive web app as a floating widget, side panel, or browser extension without rebuilding the app. It handles iframe isolation, responsive viewport geometry, lifecycle, persistence, and a capability‑based bridge to the host page. The API is simple, exposing a createOverlay function that accepts configuration for placement, launcher, and content. It is ideal for companies that want to surface internal tools or customer support widgets quickly and securely.
