/**
 * DestinationsSection — where a school's Year 11 leavers went. Server component.
 *
 * The headline is deliberately NOT the sustained-destination rate. That figure
 * sits between 92% and 97% for nearly every school in England, so leading with
 * it would say nothing; the mix is what actually varies between schools.
 *
 * The section dates its own cohort because destination measures are published
 * about two GCSE years behind the results in the section above — undated, the
 * figures read as stale rather than as a different question.
