;;; Commentary:

;; Slow integration test for the per-event :CHIME_NOTIFY_BEFORE: override.
;;
;; The unit tests call `chime--gather-info' on a hand-made org marker.  This
;; test goes one layer up: it puts a SCHEDULED heading with the property in an
;; org file, runs `org-agenda-list', and gathers events the same way
;; `chime--retrieve-events' does in the async child (split the agenda buffer
;; into lines, pull the `org-marker' from each, drop nils, map
;; `chime--gather-info').  The resulting event should carry ((30 . medium)),
;; not the global `chime-alert-intervals'.
