Overview

ErrorScreen renders an unhandled exception as a styled, centered panel instead of letting the backtrace crash into the raw terminal. Shows the exception class, message, the most relevant backtrace lines, and a dismiss hint. The Runtime displays it when a dispatched action raises and no ‘rescue_from` handler claimed the exception.
