Poster workflow
Use the event date as the shareable state, not a hidden local bookmark.
Frame Jupiter and Saturn on 21 December 2020 and print the epoch telemetry beside the orrery.
The orrery link carries the date, view and scale in the URL so the same configuration can be shared, cited, posted, inspected and printed without relying on browser localStorage.
