Unfragile

The request names tmux itself, so the answer is about tmux: a terminal multiplexer. None of the candidate sources is tmux's own page, and none describes tmux directly; they are tools that work with, wrap, or replicate tmux. Byobu wraps tmux with keybindings and profiles 3, TmuxAI is an assistant that runs inside a tmux window 1, and RMUX is a tmux-compatible multiplexer 4. Zellij 7 and tuios 8 are alternative terminal multiplexers and window managers.
