Function scope 

pub async fn scope(request: Request, next: Next) -> Response

Establishes a fresh larust_view::push_registry scope around every request - see that module’s own doc comment for what it’s for (letting @push content cross a <wire:...> mount boundary, or a .into_html()-glued layout, that @push/@stack’s normal compile-time resolution can’t see across).

Wired in unconditionally by crate::Router::into_axum_router - deliberately not an opt-in .middleware(...) call the way CSRF is, the way with_sessions’s own session layer isn’t either: an app that forgot to opt in would silently reintroduce the exact “renders as nothing, no error anywhere” failure this whole mechanism exists to close, for a feature with no visible symptom until someone actually depends on it.
