spacing between staff and tabstaff

[Walt North]

Maybe it's just because it's been a long day but I'm just not seeing 
what I'm missing.  I've tried a lot of different things but I've 
simplified a sample down below.

I'd like to have more space between the Staff and the TabStaff.

\version "2.24.4"


nts = \relative {c''4 d e f }

\score {

  \layout {
    \context {
      \Staff
      \override VerticalAxisGroup.staff-staff-spacing =
      #'((basic-distance . 3) (minimum-distance . 20) (padding . 0))
      \override VerticalAxisGroup.nonstaff-nonstaff-spacing =
      #'((basic-distance . 3) (minimum-distance . 20) (padding . 0))
    }
    \context {
      \TabStaff
      \override VerticalAxisGroup.staff-affinity = #UP
    }
  }

  <<
    \new Staff \nts
    \new TabStaff \nts
  >>
}
