Following a sync and undoing it

A sync runs in the background, so you can leave the page. A progress banner follows you across host pages. A failed run stays on the banner until you dismiss it.

The sync page shows how many trips were blocked, which trips still need a car, and every trip it read. Recent syncs keeps the history.

Undo on a run removes the trips it created and their calendar blocks, so those dates become bookable again. You confirm first. Syncing the same trip again is safe; it updates instead of duplicating.
