Implementation notes
This app requests only the three Street View Static API images that are visible on screen. It does not add hidden image tags, service workers, local image storage, or image prefetch links. On every Next action, the old second image becomes panel 1, the old third image becomes panel 2, and only the new panel 3 image is requested.
Each visible image is aimed forward along the active route. The app prefers connected Street View pano links after the first image, then scores candidates by route progress, heading alignment, and distance from the Directions route. This reduces wrong-level choices on flyovers, overpasses, tunnels, skyways, and parallel roads, but Google Street View metadata does not expose reliable roadway elevation/lane-level data, so complex roads may still need manual checking.
