  (run-hooks 'after-load-theme-hook))

(defun my-theme-config (theme)
  "Apply custom configurations based on the loaded THEME."
  (cond
   ;; Configuration for `leuven` theme (light mode)

    (set-frame-parameter nil 'ns-transparent-titlebar t)
    (set-frame-parameter nil 'ns-appearance 'light))

   ;; Configuration for `gruber-darker` theme (dark mode)
   ((eq theme 'gruber-darker)
    (set-frame-parameter nil 'ns-transparent-titlebar t)
    (set-frame-parameter nil 'ns-appearance 'dark))))

;; set titlebar based on theme
(defun title-bar-hook ()
  "Hook that runs after a theme is loaded."
  (message "Loaded theme: %s" (car custom-enabled-themes))
  (my-theme-config (car custom-enabled-themes)))

(add-hook 'after-load-theme-hook 'title-bar-hook)
