;;; test-org-capture-config--find-or-create-top-heading.el --- Tests for the shared find-or-create helper -*- lexical-binding: t; -*-

;;; Commentary:
;; cj/--org-find-or-create-top-heading is the search-or-append positioning block
;; extracted from cj/org-capture--goto-file-headline, cj/--org-capture-goto-open-work,
;; and cj/--org-capture-goto-exact-headline.  The three call sites stay covered by
;; test-org-capture-config-project-target.el (open-work, exact-headline) and the
;; target-cache test; these cover the generic helper directly with a plain regexp
;; (so the test doesn't depend on org's complex-heading format).
