Every image reference from section 6 (Code Quality & Review) through
the conclusion pointed to the wrong file (one number too high). Section
6 showed section 7's content, and so on through section 9 and all the
Tips subsections. The Conclusion reference pointed at a non-existent
28.png.
Shifting references 10–28 down to 9–27 restores the 1:1 mapping
between section content and image content. 9.png (which was orphaned)
is now used, and the broken 28.png link is resolved — the directory
only ever had 27 files.
Verified by visually inspecting 9.png/10.png/11.png/12.png/13.png/14.png
and confirming each shows the section content the doc claims.
