I am slightly confused because there seems to be a need to define some
page settings manually to get "embedded" images. In the examples in
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-lilypond.html#org2c29903,
there is no mention that we need to define page geometry. Yet, the
section is claiming that base mode "can embed LilyPond snippets into an
Org-mode file".

What am I missing?

Thanks for the clarification!

There is, but you will have to use direct Elisp to get :prologue string:

#+name: test
#+begin_src emacs-lisp
(message "This is test")
#+end_src

#+begin_src emacs-lisp :prologue (org-sbe test)
(+ 1 2)
#+end_src
