Classes

UPwa
Browser and install-state questions, plus the iOS "Add to Home Screen" walkthrough.
UWebBuild
Fingerprint of a Flutter web build — either the one a browser holds or the one the server serves.
UWebMessage
window.postMessage traffic, used by flows that hand control to a page we do not own (an IPG checkout, an OAuth popup) and wait for it to report back.
UWebUpdate
Keeps a Flutter web app on the build that is actually deployed.
