A signed auth token as it appears in contract arguments and return values.
On the wire a token occupies no calldata bytes: the runtime passes its
handle out of band, and only contracts can mint or consume one. A client
therefore only ever sees a placeholder, which this type is. TPreimage
records the token's declared preimage type for documentation; no preimage
is ever available off chain.
