Thanks for the help!

I was able to do what I was looking for with this hack (see code block
below), but now I have another problem: Some newlines are misplaced in
the *eww* buffer, for some reason. Please, continue reading.

#+begin_src dash
emacs \
  -batch \
  --eval="(setq _ (symbol-function 'kill-emacs))" \
  --eval="(fset 'kill-emacs 'ignore)" \
  --eval='(eww 
"https://www.gnu.org/software/emacs/manual/html_node/org/Introduction.html";)' \
  --eval="(add-hook 'eww-after-render-hook (lambda () (with-current-buffer 
\"*eww*\" (princ (buffer-string))) (funcall _)))"
#+end_src

I can confirm that newlines are misplaced because when I open the same
URL in a running Emacs instance (the one that I'm also using to write
this response), the following is shown in the *eww* buffer when visiting
the same URL
(https://www.gnu.org/software/emacs/manual/html_node/org/Introduction.html).

Do you know what might be causing this? Any help is appreciated.
