 Wraps [`::buffa::OwnedView`]`<`[`FlowStepActivityViewView`]`<'static>>`: the decoded view and the [`::buffa::bytes::Bytes`] buffer it borrows from travel together, so the handle is `'static` and `Send + Sync` — suitable for async handlers, spawned tasks, and anywhere a `'static` bound is required.

 Field accessors return borrows tied to `&self`. Use [`Self::view`] to get the full [`FlowStepActivityViewView`] when you need struct patterns, iteration helpers, or to pass the view to lifetime-parameterised code.*/
