// Responsive sweep: every sidebar page must lay out without
// RenderFlex/RenderBox overflow at the window sizes operators
// actually use — a small laptop split-screen, the macOS default
// window, and a full HD display. Overflow errors surface as test
// failures via FlutterError.onError, so a regression in any page's
// layout at any of these sizes fails this suite.
//
// Navigation mirrors sidebar_test.dart (fixed pumps; the app never
// "settles" because of long-lived timers).
