syntaqxg1t.sh/download opens on the visitor's own platform, with every other one a tab away. The server reads the User-Agent, so the first byte is already drawn for macOS, Windows, Linux, Android or iOS, and a phone visitor sees the phone app first; in the browser, client hints say whether a Mac or PC is Arm or x64, and an iPad asking for the desktop site is told apart by its touch screen. A switcher of the five platforms sits under a short opening, and `?platform=android` (or any other) opens that tab, which the address keeps as people switch.f68983aHistory
