Exposes a value to the query system without producing visible content.
This element can be retrieved with the query function and from
the command with typst query. Its
purpose is to expose an arbitrary value to the introspection system. To
identify a metadata value among others, you can attach a label
to it and query for that label.
The metadata element is especially useful for command line queries because
it allows you to expose arbitrary values to the outside world.
// Put metadata somewhere.
#metadata("This is a note") <note>
// And find it from anywhere else.
#locate(loc => {
query(<note>, loc).first().value
})
