Stacking Decorators — Multiple Decorators on One Function

"Real production code stacks decorators. A view in Django might have @login_required, @permission_required('admin'), and @cache_page(60). A budget function might have @validate_amount, @log_calls, and @retry. The order matters — and it's less intuitive than you'd expect. Decorators apply bottom-up (closest to the function first) but execute top-down (outermost first). Today you master stacking, understand the execution order, and learn to design decorators that compose well."
