;;; test-prog-general-open-project-daily-prep.el --- daily-prep opener -*- lexical-binding: t; -*-

;;; Commentary:
;; `cj/open-project-daily-prep' (C-c p d) opens daily-prep.org under the
;; current Projectile project root, via `cj/--find-file-respecting-split' so it
;; lands in the other window when the frame is split and reuses the current
;; window otherwise (matching `cj/open-project-root-todo').  It is
;; project-scoped: projects without a prep file get a message instead.
;; `projectile-project-root' (external project state) and
;; `cj/--find-file-respecting-split' (the window/visit boundary) are stubbed;
;; real temp directories drive the file-exists check, and the message branches
;; are checked via the command's return value rather than by stubbing `message'.
