//! Per-frame viewport context for the new input pipeline.

/// Per-frame viewport context passed to [`super::controller::OrbitCameraController::begin_frame`]
/// (and the lower-level [`super::viewport_input::ViewportInput::begin_frame`]).
///
/// Makes viewport ownership explicit so the library can apply consistent
/// hover / focus policies without each host app re-implementing them.
