Incidentally using reversed video, too, as that's what came naturally
to the terminal I was using. File is smaller, but text in the new
image is considerably more readable and the image is bigger.
The examples guideline calls for an image giving some idea what the
example is about, with a 4:3 or 5:4 aspect ratio. An image shorter
than its width wasn't practical, and getting a useful amount of
information in a height less than 3/2 of the width would have required
widening into blank space purely to satisfy the aspect ratio. The
prior image's ratio was about 12:7, the new one's is roughly 2:3.
The old image showed the start of cbordump -a output, which is rather
less illuminating than the default output of formatted data; it's also
rather verbose, so was cut off part way through. It does, however,
illustrate how the annotated form might be useful for debug
purposes. The image also had a lot of blank space to the right of the
text of interest, wasting roughly half of its width; it could easily
have been cropped to 1:1 without loss of information. As example
data-set, it used ../savegame/save.dat, but without any hint to how to
generate that.
I decided to include a hint to how to generate a CBOR data file to
dump, then show the standard output and only the beginnings of the
annotated output, as the latter (even on its own) would make the
aspect ratio considerably taller. In the context of the standard
display, the preamble of the annotated one gives a reasonable feel for
what's going on, without belabouring the point.

JSON, unlike, say, QDataStream, allows building up objects independent
of some central object, and combining them into a QJsonDocument
later. This suggests returning QJsonObjects from a toJson() const
method instead of having the caller supply a QJsonObject. Doing it
this way enables transparent move semantics to kick in, too.
For deserialization, use a fromJson() named constructor for value-like
classes (where identity doesn't matter, only equality). Keep using
read(), too, and add a note to explain when to use which form.
Also, avoid the triple lookup from
if (json.contains("key") && json["key"].isSoughtType())
mFoo = json["key"].toSoughtType();
by using C++17 if-with-initializer and showing the trick with
Undefined never being of isSoughtType():
if (const QJsonValue v = json["key"]; v.isSoughtType())
mFoo = v.toSoughtType();
Adjust the discussion to match the new code, up the copyright years
