windowInsets

NutrientMainToolbar's default insets: the ones coordinator carries in its frame (com.pspdfkit.compose.toolbar.state.ToolbarFrame.insets, settable with ToolbarCoordinator.setMainToolbarInsets), unioned with the side system bars.

The frame is how the SDK-mounted hosts — PdfActivity, PdfUiFragment — control insets when there is no call site to pass a parameter to; it defaults to the status-bar height, because the SDK mounts the toolbar edge to edge at the top of the window. A host that composes the toolbar somewhere else passes its own value instead, or NoWindowInsets when its container has already consumed them.
