# tui-smoke.sh - boot the real codex TUI under tmux in an ISOLATED CODEX_HOME
# (+ local mock model) and capture the rendered pane. SMOKE only: it proves the
# TUI launches, renders, and stays alive - it does NOT assert turn behavior
# (use app-server-drive.sh for that). The captured pane is the artifact.
#
#   --self-test       boot bare TUI, assert it renders + survives, capture pane
#   --plugin          install local omo first, then boot (proves the plugin
#                     loads in the real TUI without crashing it)
#   --seconds <n>     dwell time before capture (default 5)
