Challenge 2: Unable to Type-Correct a Spelling Mistake After Outlining Too Early — Solution Walkthrough

The answer:

Per this chapter's own warning box, outlining text is a one-way trade
— once outlined, the words themselves can no longer be edited by
typing, only reshaped point by point like any other path. By
outlining early in the design process, before the wording was fully
settled, the colleague gave up typed editability at a point when they
still genuinely needed it.

Why fixing the typo is now so much harder:

Correcting a spelling mistake in outlined text means manually
reshaping individual anchor points to change one letter's shape into
another, rather than simply retyping the correct word — a far more
tedious and error-prone process than editing live text would have
been.

How this could have been avoided:

Per this chapter's own recommendation, keeping an un-outlined copy of
the original text layer aside before outlining — the same precaution
Chapters 4 and 6 recommended for live shapes and Pathfinder results —
would have preserved the ability to fix the typo by simply editing
that original layer and re-outlining a corrected version, rather than
being stuck reshaping paths by hand.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the lost ability to type-correct text is
correctly traced back to outlining too early, and that keeping an
un-outlined backup copy is recognized as the actual preventive measure.
