The desktop strip marked the current page with a 2px underline while the mobile bottom nav already boxed it, so one navigation model looked like two. The box now sits on both: a transparent 1px border on the base reserves it, so switching pages moves no neighbours, and hover fills a fainter version of the same shape. Tools carries it too — that button is marked active for the destinations the strip hides. Dropping the mobile rule's border-bottom:none, which only existed to cancel the old desktop underline, closes the bottom edge its active box had been missing. The smoke test checks all four edges.
