// PERRY-SKIP: 'line' / 'pause' / 'resume' / 'history' — require terminal-mode interface or real stdin keystrokes.
// PERRY-SKIP: 'SIGINT' / 'SIGTSTP' / 'SIGCONT' — POSIX signal delivery, non-deterministic in CI.
// PERRY-SKIP: 'error' — only fires on stream-level failures we can't synthesize portably.
