Challenge 3: Chapter-Attribution Summary — Why This Capstone's Shape
Differs From Web Servers Fundamentals' Own — Solution Walkthrough

A sample summary:

Web Servers Fundamentals' capstone applies a decision framework
across several different scenarios, because that course's entire job
was helping the reader choose between Apache, Nginx, and IIS for a
given situation -- a question that genuinely has different right
answers depending on the scenario. Apache In Depth's capstone instead
builds one single, cohesive, production-shaped configuration, because
this course assumes that choice has already been made -- Apache was
already selected -- and its job is going deep on configuring Apache
well, not re-litigating which server to pick. A single worked example
that layers in every prior chapter is the right shape for
demonstrating depth on one already-chosen technology; a multi-scenario
framework is the right shape for demonstrating how to choose between
several.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the reader can articulate the underlying
reason two capstones look different -- tied to what each course is
actually trying to teach (choosing vs. going deep) -- rather than just
describing the surface difference in format without explaining why
it makes sense.
