;;; test-ai-term--default-geometry.el --- Tests for host-aware display defaults -*- lexical-binding: t; -*-

;;; Commentary:
;; ai-term's default display geometry is host-aware: a laptop opens the
;; agent from the bottom (75% height), a desktop opens it from the right
;; (50% width).  `cj/--ai-term-default-direction' and
;; `cj/--ai-term-default-size' encapsulate the `env-laptop-p' branch;
;; they feed the default fallbacks in `cj/--ai-term-capture-state' and
;; `cj/--ai-term-display-saved'.
;;
;; `env-laptop-p' is stubbed per-test so the assertions are deterministic
;; regardless of the host the suite runs on.
