SilentErrorBoundary#

SilentErrorBoundary#

Catches errors in a non-critical widget so it cannot take the app down.

"Silent" refers to the app, not the user: the widget used to render null, so a crashed status-bar item simply vanished and the missing readout looked like a missing feature. It now leaves a small marker whose tooltip names the component and the error, which is the difference between "this is broken" and "this was never here".
