Putting lyrics inside the staff

Lyrics can be moved vertically to place them inside the staff. The lyrics are moved with \override LyricText.extra-offset = #'(0 . dy) and there are similar commands to move the extenders and hyphens. The offset needed is established with trial and error.

\version "2.24.0"
