Struct InjectionStore 

pub struct InjectionStore;

Zero-sized placeholder so Engine::injection_store survives the #[derive(Default)] derivation when the feature is off. Arc<InjectionStore> would still allocate; ()-sized InjectionStore plus a wrapping core::marker::PhantomData keeps the field at zero bytes.
