Four tools COMPUTE rather than look up: a QR payload and its symbol size, the exact output dimensions of a resize, and the real attachment budget behind a stated mail limit. No authentication. It cannot open a vault, read a file, process an image or see anything about a user — no such interface exists on any server, and the browser tools take no input from here.",
