NA's page keys name the other locations with a problem in a blue band; PROP OUT reads Chronicles

- campuses.remote_summary -> custom variable sp_remote; band flashes until acknowledged there, steady after, "SC?" when silent
- nav_locations_band (NA only); red stays for NA's own problems
- PROP OUT: /Volumes/Location Assets/{date} on NA ProP (Chronicles share)
