Nutrient Toolbars
The SDK toolbar tree, assembled: NutrientToolbarScaffold with NutrientMainToolbar and NutrientContextualToolbar pre-wired in its slots — placement, fit-correction, drag chrome, and theming (ToolbarCoordinator.mainToolbarColors through NutrientTheme, like the ComposeView factories) all connected. The single-tree successor of PdfUiImpl mounting two ComposeViews into the View ToolbarCoordinatorLayout (Phase 4 §2); custom hosts that want the stock bars over their own content use this directly.
The content slot renders under the toolbars and reads LocalToolbarContentInset for the top space it must keep clear.
Parameters
Mirrors PdfActivityConfiguration.isDefaultToolbarEnabled.
Mirrors isDefaultContextualToolbarEnabled.
Optional host hook for handle drags (analytics).
Optional host hook reporting where the contextual bar actually renders — differs from the coordinator state when the fit correction forces a side dock to the top (see NutrientToolbarScaffold).
