Exp 10 — the document head
The title of this page was declared beside its route.
Nothing on this page wrote it. The Route file carries meta on this node, the build printed it onto the Route entrypoint, and the root Layout read it back through getContext().meta before this component ran. ursprung never looked inside the value.
An SVG title is not a head element
The mark below carries a <title>, which is how a graphic gets an accessible name. It is a different element in a different namespace from the one the document head uses, and it is served as written.
A late head element is refused
A component that opens a <title> after the document head has closed is a render error rather than a title nothing can read. This route does it and answers 500 with a correlation id, which is the ordinary path for a throw before Commit.
