   VN layout adaptation (not a restyle of unidnx's CSS).
   unidnx renders .udx-login-foot INSIDE .uni-login-main; uni-login only gives us
   a body-level footer hook, so here the foot is a sibling of the card. The body
   is a flex row (uni-login default), which lays the foot out BESIDE the card.
   Stacking the body's flex column puts the foot back directly under the card —
   the foot's own margin-top:20px then spaces it exactly as unidnx intends.
   (The toggle + canvas are position:fixed, so they're unaffected.)
