;;; Commentary:

;; tricks to speed up loading and avoid unwanted work & initialization that
;; would affect downstream init.

;;; Code:

(setq package-enable-at-startup nil) ; prevent package.el so we can use elpaca

;; Every file opened and loaded by Emacs will run through this list to check for
;; a proper handler for the file, but during startup, it won’t need any of them.
;; This is reset in posimacs-init.el after `elpaca-after-init-hook' it is reset
;; to the original value.
