+;; HACK: Doom sets `custom-dont-initialize' during the early parts of its
+;;   startup process. This stops tex-site's setter on `TeX-modes' from
+;;   activating in `tex-site', which auctex loads *very early* from its
+;;   autoloads file. `tex-site's existence is hacky (more a historical artifact
+;;   and necessary evil, given its conflicts with the built in latex modes), so
+;;   I fix it as a one-off problem rather than a systemic one.
