Exercise 2: Why the Controller Still Wins — Possible Solution
====================================================================

WHY THIS CHAPTER STILL RECOMMENDS THE CONTROLLER
------------------------------
Per this chapter's own central finding, the destination this chapter recommends - real logic living in the Controller, not the template - is the same destination Django's own architecture reaches. Keeping the breadcrumb-building logic out of the view keeps the view simple, testable in isolation, and consistent with how the rest of a well-organized Laravel application is typically structured, even though Blade technically permits doing it inline.

THE DIFFERENCE IN HOW EACH FRAMEWORK ENFORCES THIS
------------------------------
Per this chapter, Django's DTL makes the tree-walking loop structurally IMPOSSIBLE to write in a template at all - there is no choice involved; the language itself prevents it. Blade makes the identical logic genuinely POSSIBLE to write in a template via @php, and reaching the same "thin view" outcome depends entirely on the developer choosing to follow that convention rather than being forced to by the language. One is a hard language limitation; the other is a voluntary discipline that has to be actively maintained rather than being guaranteed by the tooling itself.

WHY THIS WORKS AS AN ANSWER
------------------------------
It correctly explains that both frameworks reach the same practical "logic belongs outside the template" outcome, and correctly distinguishes Django's structural enforcement (the language prevents it) from Laravel's conventional enforcement (the language allows it, but disciplined practice avoids it).
