Standalone cmd that runs the same pipeline as the webhook notifications (alerts.LoadErrorEvents -> alerts.DetectAlerts -> cooldown suppressor) on a schedule and renders what is firing as a row of severity-colored cards - built for an ultra-wide, low display. A pattern shows PAGED when the scan would have notified and ongoing while suppressed; disappearing spikes are reported as recovered. -once prints one snapshot for cron/pipe use. Colors follow the otel-ui design-system tokens (dark and light).
