ui

Serving the web app at /, the built UI under /ui/, the web app's manifest, and the template schema.

The web app's page is served at the root, so the server's address is the web app's and a sign-in lands there; its assets, the pages the extension and the mobile app frame, and its service worker stay under /ui/, where the worker's scope keeps it off the sessions of the origin. /ui/ itself sends the browser to /, so an older link or a provider's return still arrives.
