Everything below is the real app.
Not screenshots and not a mock-up: every screen on this page is rebuilt in the browser at the device's real point sizes, from the SwiftUI source. The Mac window is 1000 × 620 pt on a 16-inch display; the phone is an iPhone 393 × 852.
A .NET backend on one Mac, clients on macOS, iPhone, iPad and Apple Watch, and a SignalR connection carrying every agent's output live to all of them.
Nothing here is faked. Where a control does not exist in the app, it is not drawn.
