A manifest and icons rendered from icon.svg make the app installable. The native build emits a service worker that precaches exactly the built files and passes everything else to the network, so ROMs never reach its cache. New versions wait for the player's Update, which saves before reloading. Savegames offers installation, iPhone steps and persistent storage, and a full disk gets its own save error. Acceptance on physical iPhone and Android devices remains. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
