[ns-ui] A card-scale ambient loader modelled on caddisfly larva case-building: mineral grains drift in one at a time, get measured against the open gap at the case's growing rim, and either cement into place (extending the tube in a slow spiral) or get rejected and drift away, working around the rim course
