;;; test-ai-term--capture-state.el --- Tests for cj/--ai-term-capture-state -*- lexical-binding: t; -*-
;;; Commentary:
;; The capture helper writes WINDOW's direction and size to module-
;; level state vars `cj/--ai-term-last-direction' and
;; `cj/--ai-term-last-size'. Called from `cj/ai-term''s toggle-off
;; branch so the next F9 display can restore the user's chosen
;; orientation and size. No-op on a dead window.
