Контракт

• UntaggedPhantom<i32, String> implements Unpin despite containing a PhantomPinned field because pin_project! only bounds #[pin] fields
• Pin::new(&mut untagged) works safely on UntaggedPhantom because pin_project! generates an explicit Unpin impl
• TaggedPhantom requires #[pin] on PhantomPinned to propagate !Unpin to the struct
• AttributeNotUnpin uses #[project(!Unpin)] to suppress the automatic Unpin implementation entirely
• project() returns Pin<&mut T> for #[pin] fields and &mut U for unpinned fields
• project_ref() returns Pin<&T> for #[pin] fields and &U for unpinned fields
• project_replace replaces the struct in-place and moves out unpinned fields by value
