A teammate proposes a classic `static Instance` Singleton for a `PricingConfiguration` class used across a service. Why do many senior engineers push back on that, and what do you use instead in an application that already has a DI container?

Explain the difference between Factory Method and Abstract Factory using a concrete scenario, such as a system that must send notifications through different channels and also build channel-specific templates and delivery receipts. When is either one overkill?

When is the Builder pattern worth using compared to a constructor with many parameters, object initializers, or C# `record` types with `with` expressions? Give an example where you would not use it.
