 - The transcript is a plain `VStack` in a `ScrollView`, not lazy: a `LazyVStack` estimates the height of rows it hasn't shown yet and corrects it when they scroll into view, without moving the scroll offset, so scrolling up through rows not yet shown jumped by each correction; SwiftUI can't move the offset mid-scroll without stopping its momentum.
 - The terminal cursor is a steady block: SwiftTerm's blinking cursor restarts its Core Animation fade on every keypress, scheduled 0.7 s out, and on a ProMotion display macOS then holds the window's screen update until that fade starts, so each typed letter appears about 0.7 s late. SwiftTerm redraws the whole screen whenever a terminal color is set, even when its value hasn't changed.
+- A full-size diagram is drawn at its zoom, in tiles, and a pinch is folded into that zoom when it ends. Scaling a natural-size SwiftUI view down with `NSScrollView` magnification or `UIScrollView` zooming draws only about a window's width of it, so fitting a wide diagram that way shows its first few boxes and blank space.

 - The Page view loads a worktree page from a plain-HTTP server the app runs on a loopback port (`http://127.0.0.1:<port>/<task id>/<path>`), which fetches each file through the server's `getTaskRaw` endpoint. The page's relative links to its stylesheets, scripts and images resolve to files beside it; absolute and `file://` references don't load. "↗ Browser" opens the same address. iOS reclaims the listening socket while the app is suspended, so the app binds it again on the same port each time it returns to the foreground. Previews load from their loopback forwards at `<name>-<task>.localhost`. App Transport Security blocks plain HTTP to `*.localhost` even with `NSAllowsLocalNetworking`; the `localhost` exception domain with subdomains in `Info.plist` allows it (loopback IP addresses need no exception). `NSAllowsArbitraryLoadsInWebContent` lets the Page view load plain-HTTP websites without lifting ATS for the app's own requests.
 - Each Page view tab's `WKWebView` belongs to `Pages`, not to the SwiftUI view, so it keeps its page while the sheet is closed and agents can drive it with `drive_page` (navigate, JavaScript, capture) from the client connection. All tabs share WebKit's default persistent data store, so a site the human signs into stays signed in across launches. A link that opens a new window becomes a new tab of the same task. Capture refuses a tab that isn't on screen (sheet closed, or another tab showing), since its snapshot would show nothing the human sees. Passkey sign-in may fail, because WebKit allows WebAuthn in an embedded view only for apps with Apple's web browser entitlement; a password with a 2FA code works.
