Thanks!  This showed me how to do a different tweak: positioning a \mark
above all other notation on a staff.
(presented here for the same at-home audience)

{
\override Score.RehearsalMark #'Y-offset-callbacks = #(list
Self_alignment_interface::aligned_on_parent
)
  c1^1^2^3
\mark Foo
  c1
\override Score.RehearsalMark #'self-alignment-Y = #0.7
  c1^1^2^3
\mark Foo
  c1
}
