There was "lt 3", but the lines were dashed. Yes, I know that I could
ask the terminal to plot all the lines as "solid", but I have tried
"lt 1 lc 3" instead, which works in most other cases, but produced
strange results in this particular case.

I thought that lt 1 lc 3 should create a solid line with the same
color as if I would select lt 3.

But I don't know much about 3D plots in gnuplot anyway, so I might
have been mistaken.
