New in-theme classes: Buyers computes a shopping-list total, PriceList stands for the pricing service (random surge, flaky test). One loop, one lambda-able expression — the third example teaches the move with nothing else in the way. Pristine repo + reference solution (extract lambda, slide, extract method with Func<IceCream,int> parameter, pure-lambda test) + storyboard in the established style. Mirrors the kata's C# setup (net7.0, MSTest); needs a build check on a machine with the SDK.
