The finished-game export (GCG + a new PNG of the final position) is one signed, short-lived relative URL (game.export_url; HMAC-SHA256, 10-min TTL, BACKEND_EXPORT_SIGN_KEY) resolved against the client's own origin and delivered by the best affordance each platform has (five on-device review rounds): - TG Android/desktop: native showPopup chooser -> native downloadFile dialog (bridge-only chain, activation-safe). - TG iOS: app-modal chooser -> OS share sheet with the fetched file (a popup callback cannot supply the activation the sheet needs). - VK iOS: VKWebAppDownloadFile for both formats. - VK Android: the PNG opens in VK's native image viewer, the GCG copies to the clipboard (the VK Android downloader hangs on any download, Content-Length/Range notwithstanding). - VK desktop iframe / desktop browsers: plain anchor downloads. - Mobile browsers: the OS share sheet (fetch-then-share). - Legacy TG (< Bot API 8.0): app modal + GCG clipboard, no image option. The PNG is rasterized on demand by the new internal `renderer` sidecar (node:22-slim + skia-canvas + baked Liberation/Noto Color Emoji fonts) executing the SAME ui/src/lib/gameimage.ts the ui project unit-tests; the backend rebuilds the render payload from the journal + engine.AlphabetTable, and the device date locale, IANA time zone and localized non-play labels ride the signed URL. Nothing is stored — the artifact re-derives from the immutable journal on each GET. The gateway forwards /dl/* (caddy @gateway matcher extended) behind the per-IP public rate limiter and serves bytes via http.ServeContent. Deploy: renderer service in compose + prod overlay + rolling order + prod push list; TEST_/PROD_EXPORT_SIGN_KEY secrets; the sidecar smoke runs in the ui CI job. Docs: ARCHITECTURE, FUNCTIONAL(+_ru), UI_DESIGN, TESTING, deploy/README, renderer/README.
