   the body — the small print and the buttons — drifted to a different height in each one (seen on /sign-in,
   16 Sep 2026). The body is the part that varies, so the tail of the card is pushed to its foot as one
   group: the buttons sit on the same line across the row, and the note sits directly above them.
