Build a responsive Claude Agent Notification Widget. Design a utilitarian + pixelated dark UI: monochrome blacks/charcoals with one accent color. Use a pixel font for labels and a readable monospace for values/logs. The widget card should show: status (RUNNING/IDLE/SUCCESS/FAILED), task name + current step, token count, time elapsed, a progress bar, and a terminal-style activity log with scrolling output. Add simple pixel-style borders and a subtle blinking cursor indicator when running.
