Reviews the stack against 2026 alternatives and finds no swap worth making: Street View is priced out, MapLibre would fight the panorama viewer for the GPU, Pannellum trades away the gestures the game runs on. The findings that matter are mobile playability, panorama weight, and the Turf monolith reaching the browser through a client-imported module. Also records an unverified Mapillary bbox constraint that four of five cities would sit exactly on.
