Pure reformatting, no content change. Each bullet/paragraph is now one
logical line instead of manually wrapped at ~80-100 chars, which looked
ragged with short trailing fragments in narrow/variable-width editor
panels. Editors soft-wrap long lines naturally; manual hard wraps don't
adapt to panel width.
Also gave the orphaned "Wallpaper reliability" item (previously sitting
between two --- dividers with no section header and a stray double
blank line) its own section header for consistency with the rest of
the doc.
