tmux.GlobalWindowScope.SetCopyModeMarkStyle(ctx: context.Context, value: string) -> error
```

SetCopyModeMarkStyle stores the "copy-mode-mark-style" window option as string (tmux 3.2a or later). Read it with [WindowOptionValues.CopyModeMarkStyle] from [GlobalWindowScope.Options]; [GlobalWindowScope.UnsetOption] restores inheritance or the global default.
