I was fooling around with the Settings panel and must have done
something I shouldn't, because now the fonts for KDE apps are all

illustrate. Note that the left-hand side looks fine, while the right-
hand side is clearly wrong. The same fuzziness affects the Plasma panel
and the Konsole fonts.
I've no recollection of touching the font configuration, but I guess
anything is possible. How can I restore sanity?
Still no idea what happened, but after trolling through a backup and
'diff'ing some files, the culprit turned out to be lurking in
~/.config/fontconfig/fonts.conf, which had some missing lines.
Restoring it fixed the problem.
