mobile/vision/index.html is a single self-contained file: a hand-written WebGL2 planet with real sun position, Black Marble lights, atmosphere, clouds and a mobile post chain; the full feed, card-to-world morph, Ride, lenses and time ribbon over synthetic traffic; capture with real WebCrypto seals; and reconstruction threads with a verifiable ledger and an AI refine composer. All data is illustrative and marked as such. build.mjs regenerates it offline from src/ and assets/.
