(panes observation)

Primary method: libtmux:snapshot:
(panes (snapshot libtmux:snapshot))

Primary method: libtmux:window:
(panes (window libtmux:window))
```

Return a fresh vector of captured physical panes, without I/O.
Snapshots preserve first occurrence; windows preserve the captured pane order.

## Methods

### `(panes (snapshot libtmux:snapshot))`

### `(panes (window libtmux:window))`

## Parameters

- `observation` (for `panes(observation)`)
- `snapshot` (`libtmux:snapshot`) (for `Primary method: libtmux:snapshot`)
- `window` (`libtmux:window`) (for `Primary method: libtmux:window`)
