Christian Tietze had a [[https://christiantietze.de/posts/2022/02/emacs-tab-bar-numbered-tabs/][great idea]] for making the tab-bar numbers more distinguished from the labels on the tabs (he has a [[https://christiantietze.de/posts/2022/12/sf-symbols-emacs-tab-numbers/][follow up essay]] about using a different font, Unicode is more portable and looks fine).

#+BEGIN_SRC emacs-lisp :tangle no
