/**
 * Post16DestinationsSection — where a school's Year 13 leavers went.
 * Server component.
 *
 * A separate publication, a separate cohort and a separate question from
 * After Year 11, so it is a separate section rather than a tab: a parent
 * choosing a secondary and a student choosing a sixth form are not the same
 * reader.
 *
 * Not rendered at all for a school without post-16 provision. A "no data"
 * placeholder there would imply something is missing, when the truthful
 * statement is that the question does not apply — which is why the old
 * "Post-16 destination data coming soon" note is gone rather than reworded.
