Challenge 3: Why This Capstone's Shape Fits This Specific Course — Solution Walkthrough

Summary:

Web Servers Fundamentals' own capstone applied a decision framework
across several different named scenarios, since that course was
fundamentally comparative — choosing between Apache, Nginx, and IIS
for different jobs. Nginx In Depth's own capstone instead built one
single, cohesive production configuration, since that course was a
single-technology deep dive with nothing left to compare. This
course's own capstone takes a third, distinct shape again: one real
photo, worked through step by step, with both tools' own workflows
shown side by side at every single step.

Why this shape fits this specific course:

This course's own central premise, established in Chapter 1, is that
Photoshop and GIMP share a discipline rather than a platform — every
concept needed to be taught once, then shown concretely in both tools.
A capstone that only chose one tool per scenario (the Web Servers
Fundamentals shape) would abandon that side-by-side comparative
structure right at the finish line. A single-config build (the Nginx
In Depth shape) has no natural equivalent here, since there's no
single "configuration" to assemble — retouching one photo well is
itself the deliverable.

Why parallel execution is the natural fit:

Showing both tools' own workflow at every step of one real project
directly continues the comparative promise this course made from
Chapter 1 onward, letting the capstone reinforce the exact structure
the whole course was built around, rather than switching to an
unrelated format just because it worked well for a different kind of
course.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the relationship between all the capstone
shapes seen across this session's own courses is understood as a
deliberate match between each course's own actual teaching goal and
the capstone format best suited to demonstrating it — here, genuine
tool-by-tool comparison sustained through to the very end.
