Rides in the existing payload rather than a new endpoint: the page already makes one server fetch for its data, and /school/[slug] regenerates weekly, so the per-request cost is paid once per school per week. Wrapped so a failure in selection never 500s a page that is otherwise complete — the posture get_supplementary_data already takes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
