- Street Level is rebuilt around one small provider registry: Mapillary,
  KartaView, Panoramax and Google Street View share one coverage drawer and
  one photo viewer, one source lit at a time. Floating and docked panels,
  FOLLOW, surface modes, the legend and the Mapillary proxy's disk cache are
  gone; `.gev-cache/mapillary/` from earlier runs is no longer read and can be
  deleted (gekh, #974).
