One sidebar entry: 16px icon, label, optional count or an amber hold / stuck pill, nested children for Settings and Website. The current item gets a 2px periwinkle rail.
Lifted from the approved family page at build time; interact with it.
One row per page in the registry. Counts are live; amber means someone is waiting on it.
