preparing for cloud work1// The desktop bridge: what the site finds at `window.g1tDesktop`, run at
2// the start of every page the window loads (bridge.rs puts it there). The
3// site's lib/notify-client.ts describes the contract from its side; when
4// the bridge is there, notifications go to the system, the badge to the
5// icon, links out to the browser, and g1t:// links arrive as `onNavigate`.
6// Each call is a command in bridge.rs, which only answers the server's
7// pages; on any other page the calls fail quietly.
