      "The checked official WebAssembly bytes are injected into Module.wasmBinary so runtime startup requires no fetch or connection permission.",

      "Trailing whitespace is removed from the adapted inlined runtime output; the retained official JavaScript artifact remains byte-exact.",
      "The host bridge gates animation frames and all game input until explicit start, pauses frames while paused, and adds a touch mark mode that maps taps to the original right mouse button.",
      "The official HTML is wrapped in a local no-network document with a restrictive CSP; external page chrome and links are hidden from the game surface, and a source comment containing a script-close token is escaped before inline delivery.",
      "Losing focus from the running opaque frame notifies the host and pauses the puzzle; resuming requires an explicit player action."
