feat(intro): v2 — cities, accelerating sweep, detections, thriller sound design

- City engine: Esri ground, OSM buildings that rise with the scan, road
  ribbons carrying modelled traffic coloured by congestion, NYC DOT cameras,
  real ADS-B, MBTA GTFS lines + realtime vehicles, LAX runways with approach
  strobes, Fort Bragg restricted volumes, Everest terrain with contours.
- Indexing keeps accelerating into a 260-capture global sweep while the
  planet whips a full turn.
- The eye opens: aperture blades, sensor array waking, optics calibration,
  radar sweep, orbiting coordinate ring.
- Camera wall with YOLOv8n detections and a city-pulse trace.
- Ends on GOD'S EYE VIEW / OMNISCIENCE.
- audio/sfx.py: sound design only, built to sit under a music track.
