Mockup — not the live app. The strike data here is invented so the interaction can be judged. Proposed: the period dropdown is replaced by a vertical scrub timeline, the way a camera review works. Now is at the top; time descends into history. Drag the rail or use the wheel over it to travel back. + / − zoom from 30-second to 30-minute resolution. The map shows the moment you're parked on. Live snaps back to now and resumes following. Past minutes never move or rescale — what happened, happened.
