/**
 * The single seam between the characterization tests and the component tree.
 *
 * This file is the ONLY thing the server/client split was allowed to change.
 * It now renders the shell + server-sections composition that
 * app/school/[slug]/page.tsx builds, instead of the old monolithic views.
 * Every assertion in schoolDetail.characterization.test.tsx is unchanged —
 * that is the proof the refactor preserved behaviour.
