2 : * @file test_tui_resize.c
3 : * @brief PTY-04 — tg-tui SIGWINCH resize repaints screen.
4 : *
5 : * Verifies that tg-tui:
6 : * a) Starts at 80×24, shows "[dialogs]" hint.
7 : * b) After PTY resize to 60×20 + SIGWINCH, repaints and still shows
8 : * "[dialogs]".
9 : * c) After resize back to 80×24, repaints again.
10 : * d) Exits cleanly (exit code 0) when 'q' is pressed.
11 : *
12 : * Approach:
13 : * - Same stub-server setup as PTY-02 (pty_tel_stub seeds session.bin).
14 : * - pty_resize() issues TIOCSWINSZ on the master fd and delivers SIGWINCH
15 : * to the child, then pty_settle() waits for the repaint to settle.
