 * you to check the pane. None of that is actionable on a device — the reader cannot follow a URL, and a
 * long sentence pushes the one fact that matters off the card. So each rule here keeps the WHAT and the
 * WHEN and drops the rest, rather than truncating, which cuts the end — where the useful part usually is.
