IViewModel

using aria::binding::IViewModel = ViewModel

IViewModel is an alias for ViewModel, provided for users coming from WPF / Avalonia / MAUI where the IViewModel spelling is canonical.

Note that despite the I prefix this is NOT a pure virtual interface — ViewModel is a concrete base class with state (is_active, subscription bag, child list, destroy hooks) and default implementations for on_activate / on_deactivate. The IView / IViewAdapter types in this library really are pure interfaces and keep the I prefix; ViewModel does not, because hiding its stateful nature behind an I would be misleading. This alias exists purely to match external naming conventions without forcing the rename on internals.

Presentation

enum class aria::binding::Presentation : unsigned char

strong

How a navigation entry is presented to the user.

Push slides onto the back-stack; Modal overlays without disturbing the previous active page (the modal's parent stays "current" from current Property's perspective in some adapter conventions, but Navigator picks the topmost entry as current regardless – the adapter is responsible for rendering the modal as an overlay).
