LibTmux.PsmuxPane.CaptureAsync(options: PsmuxCaptureOptions?, cancellationToken: CancellationToken) -> Task<IReadOnlyList<string>>
```

Reads this pane's text through the audited capture subset.

Target consistency is best effort. An external process can remove the
pane between LibTmux's existence preflight and psmux's capture.

## Parameters

- `options` (PsmuxCaptureOptions?): The typed capture range and rendering choices.
- `cancellationToken` (CancellationToken): Cancels the psmux query.

## Returns

The captured lines.

## Raises

- `InvalidOperationException`: The selected namespace has no live session.
- `StaleServerGenerationException`: The sole session was replaced after this observation was read.
- `NotSupportedException`: The selected namespace contains more than one session.
- `TmuxObjectNotFoundException`: The observed pane is no longer visible during the preflight.
- `LibTmuxException`: The verified client could not complete the query.
