Complex architectural changes are difficult to grasp purely from raw code diffs. Visual tools like PR Lens allow developers to convey data flow transitions and service boundaries clearly during code reviews.
The showcase demonstrates a standard backend refactoring pattern: decoupling latency-sensitive user requests (HTTP sign-up) from slow external I/O (email sending) using an event queue. By mapping the changes into a sequential walkthrough, reviewers can inspect how stores, routes, and workers evolve across the pull request.
