Nothing unusual, statistically speaking.  Emacs crashes and freezes on
macOS now and then.  I just wanted to give you a thorough account of
what exactly I did.

So, I did the following:

+ removed Emacs 29
+ installed Emacs 28.2
+ recompiled Org Mode with 'make'
+ deleted '~/.emacs.d'
+ made sure cache/overlays remain enabled in '.emacs'
+ opened 'notebook.org'
+ initiated Org export to HTML
+ got 's-matches-p: Wrong number of arguments: #<subr string-match>, 4'
+ figured out WTF
+ added MELPA
+ installed 'citeproc' and 'htmlize' (should ship with Emacs, IMO)
+ opened 'notebook.org' again
+ enabled profiling
+ initiated Org export to HTML again
+ waited for 1 minute and 35 seconds
+ saved 'emacs-28-org-export.profile'
