+# The ai launcher's --runtime flag: pick the agent CLI (claude, codex) that
+# a project window launches. Part of the generic-agent-runtime arc — the
+# tmux-side counterpart of .emacs.d's ai-term multi-LLM handoff. The
+# --print-launch mode exists for exactly these tests: it prints the launch
+# command a real run would send to the pane, without touching tmux or fzf.
