How this example is put together

A note explains the content around it. It is set apart by its box, and by nothing else. There is no tint, no level, no claim about anybody.

A tip has no title, which is the common case. One short paragraph, next to the thing it is about.

What this example leaves out

A caveat names a specific, checkable limitation of what is on screen. It says how a figure was worked out, or what it does not include.
