"""Split terminal : diviser un onglet en 2/4 panneaux, deplacer un onglet dans
un panneau, fermer un panneau (redescente automatique a un onglet simple),
fermeture globale d'un onglet divise.

SSHConnection.start() et LocalTerminalConnection.start() sont neutralisees :
ce module teste l'agencement des panneaux et le cycle de vie des onglets, pas
une vraie connexion (deja couverte par test_keepalive.py / test_bastion.py)."""
