> Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted. Read the text a pane is showing, and optionally its scrollback. The newest lines are always kept; anything dropped to fit the budget is reported. To watch a pane across several turns, use capture_since instead — it returns only what is new.
