// The header's bell reads `/gear-service-due` on each navigation, but a schedule,
// a service record, a dive or a gear item saved on the page under it moves a due
// figure without one - and there is no shared cache between them to notice. The API
// calls that can move one announce it here, so every route to them is covered.
