Exercise 3: Correcting "WordPress Needs a Page Builder to Be No-Code" — Possible Solution
====================================================================

WHAT THE LEARNER'S ASSUMPTION GETS WRONG
------------------------------
Per this chapter's own tip-box, "it's a common mistake to assume
WordPress requires a separate page-builder plugin to be no-code at
all. It doesn't - the Block Editor alone already delivers real no-code
content editing." WordPress's own native Block Editor, covered in
WordPress Fundamentals 4, is itself a genuine no-code tool - building
posts and pages from blocks, patterns, and reusable blocks, with zero
PHP required, entirely independent of whether any page builder plugin
is ever installed.

WHY THIS MATTERS FOR CORRECTLY UNDERSTANDING WORDPRESS'S OWN POSITION
------------------------------
Per this chapter's own opening, Chapter 1's spectrum table already
separates "self-hosted CMS alone" (plain WordPress) from "self-hosted
CMS + page builder" (WordPress plus something like Elementor) as two
DIFFERENT, both genuinely no-code positions - not one no-code position
and one code-required position. The learner's assumption collapses
this real distinction into "WordPress is code-only until a page
builder is added," which contradicts what Chapter 1's own table
already established.

WHAT A PAGE BUILDER ACTUALLY ADDS, GIVEN THAT PLAIN WORDPRESS IS ALREADY NO-CODE
------------------------------
Per this chapter, a page builder adds "a more Wix-like freeform,
drag-and-drop visual builder" specifically for full page/site-wide
LAYOUT control (potentially including headers and footers) - not
"no-code capability" in general, since that capability already exists
via the Block Editor. The real addition is a different, more freeform
style of visual design work, not the presence or absence of code
requirements altogether.

WHY THIS DISTINCTION IS WORTH CORRECTING SPECIFICALLY
------------------------------
Believing WordPress "requires" a page builder to be no-code could lead
someone to install one unnecessarily, taking on the real performance
and lock-in costs this chapter names, for a capability (basic no-code
content editing) they already had access to through WordPress's own
core Block Editor at no additional cost or complexity.

WHY THIS WORKS AS AN ANSWER
------------------------------
It cites this chapter's own explicit correction of the exact
misconception in the exercise, ties the correction back to Chapter 1's
own spectrum table distinguishing the two positions, and explains
precisely what a page builder actually adds once the false premise (no
no-code capability without one) is removed.
