CaptureRequestError reports a [CapturePaneRequest] field that cannot be represented as a tmux capture-pane argument. It matches [ErrInvalidCaptureRequest] through [errors.Is] and is available through [errors.As].

## Members

- `Field` (attribute) — Field names the invalid request field.
- `Value` (attribute) — Value is the rejected field value. It may be empty when absence is the error.
- `Reason` (attribute) — Reason describes the violated request constraint without promising a stable complete error string.
- `Error` (method) — Error implements error.
- `Unwrap` (method) — Unwrap makes CaptureRequestError compatible with ErrInvalidCaptureRequest.
