Challenge 2: Reordering Slides in Slide Sorter View — Solution Walkthrough

Setup: 5 slides, each with different placeholder text. Slide 5 is
dragged to become slide 2 in Slide Sorter view.

What happens to the content of every other slide:

Nothing about any individual slide's own content changes at all —
every slide's text, images, and layout remain exactly as they were.
The only thing that changes is the SEQUENCE the slides appear in:
what used to be slide 2 becomes slide 3, the old slide 3 becomes
slide 4, the old slide 4 becomes slide 5, and the moved slide (old
slide 5) is now slide 2. Each slide is simply relabelled by its new
position — none of them had their internal content touched, resized,
or reformatted by the move.

Why this has no real equivalent in Word:

A slide is a genuinely independent, self-contained unit — moving it
is purely a matter of changing its position in an ORDERED LIST of
otherwise-untouched objects, which is exactly what Slide Sorter view
lets you do by dragging. Word has no equivalent discrete unit to drag
in the first place — there's no "paragraph 3" object sitting
independently that could be relocated as a single whole while every
character inside it stays byte-for-byte identical. Reordering content
in Word instead means physically selecting text and cutting/pasting
it into a new position within the SAME continuous stream — an
operation that risks picking up or leaving behind stray formatting,
extra line breaks, or partial selections, none of which are even
possible risks when dragging a whole, self-contained slide.

Notes:
- This directly demonstrates this chapter's own claim that a slide is
  "the closest thing PowerPoint has to Excel's own independent,
  addressable unit" — reordering slides works cleanly specifically
  BECAUSE each one is a genuinely separate object, the same reason a
  cell's own value doesn't change when a different cell elsewhere on
  the grid is edited.
