Type Alias CacheTalcLock 

pub type CacheTalcLock = Talck<RawSpinlock, ErrOnOom>;

Concrete Talck flavour used by the shared state-cache region.

spinning_top::RawSpinlock for serialisation (no lock_api direct dep needed downstream); ErrOnOom so OOM returns Err rather than attempting heap extension — callers hand talc its backing memory up front via Talc::claim.
