/**
 * PrimarySchoolSections — the section sequence for primary and all-through
 * detail pages. Server component.
 *
 * All-through schools route here rather than to SecondarySchoolSections,
 * because this list renders BOTH the KS2 and KS4 blocks (ResultsSection and
 * HistorySection branch on isAllThrough); the secondary list is KS4-only and
 * would silently drop their SATs data.
 *
 * The render conditions here MUST match buildNavItems in lib/schoolSections,
 * or the sticky nav will link to sections that do not exist.
