M1: PageErrorBoundary wraps the body of every InteractiveServer page; the inert layout boundary is removed. m1: DisposeBridge cancels its CTS when the 5 s wait times out. m2: a CSV import that commits after the modal closed still raises OnSaved. m3: document SecurityMode=None no-fallback in Client.CLI.md / Client.UI.md. m4: browsePageDelayMs written only when loaded or changed; negative flagged.
