Both detail views fetched /api/national-averages in a useEffect, so the
England-comparison deltas popped in after hydration and every section that
uses them was pinned to the client. The page now fetches it in parallel with
the school details (backend-cached 1h, degrades to null) and passes it down.
Removes one client round-trip per detail page and unblocks the section
extraction.
Characterization tests pass unmodified; only the render helper changed.

14 characterization tests covering Ofsted (both OEIF and Report Card layouts),
KS2 results with the England delta, KS4 Attainment 8 / Progress 8 / EBacc,
all-through dual rendering, special-school comparison suppression (PR #70),
the admissions year/trend toggle, and conditional section rendering.
All rendering goes through renderSchoolDetail(), the single seam the
server/client split is allowed to change. The assertions must survive the
refactor unmodified.
Excludes __tests__/support from testMatch: it holds fixtures and helpers, not
suites, and the glob was failing them as empty test files.
