```
capture(Pane, Options)
-spec capture(tmux_model:pane(), capture_options()) ->
                 {ok, binary()} | {error, map()}.
```

Capture terminal bytes, preserving final newlines. Options select line range, joined wraps, escapes, alternate screen and padding; defaults follow tmux current-screen capture. Performs I/O and returns an explicit output-limit error instead of silently truncating.

## tmux command

The tmux commands behind `capture/2`.
