Argues the best architecture is dictated by project requirements and shows concrete separations: session vs long‑term storage, UI platform, presentation/control/compute/build logic.

Replaces heavy libraries by standard library code (example: an HTTPUrlConnection network call) to get fast unit tests and even achieve 100% test coverage on a Sudoku generator. Warns Gradle config for KMP is currently painful.
