The command for the pane's trusted POSIX-compatible shell.

Shell reserved words and special builtins must retain their standard
meanings. The command runs inside a subshell, so several lines are fine
and a bare `exit` does not end the pane's own shell. Invalid syntax is
contained and completes with the shell's nonzero status. Valid inherited
Bash and zsh `ERR` and `DEBUG` traps remain visible to the command while
the pane's parent-shell traps and options remain unchanged.
