- Play a cover-scaled video between systems on jump, with an opaque backdrop so the source doesn't show through
- Double-click skips the remaining clip; single press is swallowed while it plays
- Fall back to the short jumpDelayMs cut when no video is configured or missing
- Guard against stalled/overlong playback with a grace and duration cap before restarting
- Add assets/videos/jump.mp4 and document the new behavior in gates.json and PROJECT_NOTES.md
