TudorandClaude Opus 4.8 ae6ef6860b fix: don't portray special schools as failing the mainstream benchmark

Special schools, PRUs and alternative provision teach pupils with SEND who
sit the same KS2/KS4 assessments but very few reach the mainstream "expected
standard". Their headline attainment is therefore ~0% (or a very low
Attainment 8), and the site was comparing that to the England average and
painting it red — e.g. Greenmead School (a community special school) rendered
as "0.0% — −62 pts below England average" with three 0% red SATs bars. That
portrays a special school as catastrophically failing against a benchmark
that doesn't fit it.

Add a shared `isSpecialSchool()` helper (detects every DfE special-school
establishment type — all contain "special" — plus PRUs / alternative
provision) and drop the mainstream England comparison + "below" framing for
these schools across every surface:

- Detail (primary + secondary): a plain-English context note explaining the
  school is special and why the comparison isn't shown; England-average delta
  chips, "England avg" hints, the SATs national markers, the Attainment-8
  "vs national" bar and the trend chart's England overlay are all suppressed.
  An all-zero placeholder SATs row hides the (empty) subject bar chart and the
  "why is combined lower" bridge.
- Rankings / search rows (primary + secondary): the mainstream RWM / Attainment
  8 stat shows "—" with no "vs national" delta, instead of "0% · −62 vs
  national".
- Compare: special schools' attainment values are dropped (no misleading dot
  at 0% / no "Below England average" chip); progress banding, which IS a fair
  measure for special schools, is kept.

Belt-and-braces zero-guard: a whole-row zero attainment (special or a
suppressed cohort) is also treated as not-comparable, while a legitimate
single 0 (e.g. 0% exceeding at a mainstream school) stays comparable.

Tests: new isSpecialSchool unit tests (every DfE special type matched, no
mainstream false positives); an e2e journey asserts Greenmead shows the
special-school note and no England-average comparison. tsc clean; 108/108 unit.

TudorandClaude Fable 5 b0c5b6bb57 fix(compare): anchor grade-5 & EBacc rows; restore secondary-button outline

SF1 (expert sign-off): the secondary academics 'Grade 5+ in English &
maths' and 'EBacc entry' rows rendered as bare numbers — the one place
the 'every number anchored against the England average' promise broke.
Both now show the official England anchor (already in the payload) + an
Above/Close/Below verdict chip, matching Attainment 8 (which also gains a
chip for consistency).

Button affordance: globals.css has a duplicate .btn block whose
'border: none' overrode the base '1px solid transparent', so
.btn-secondary/.btn-active's 'border-color' had no width — every outline
button (the modal's '+ Compare', search-result '+ Compare', 'Comparing')
rendered as borderless teal text. Give the outline variants the full
'border' shorthand so the outline renders regardless of the clobbered base.

TudorandClaude Fable 5 200a97d0b9 fix(compare): per-school P8 explanation; disadvantaged cohort from the same yearly row

Review findings: (1) the 'no KS2 baseline (COVID)' explanation was derived
from the basket-wide max year, so a school with an unrelated data gap
borrowed it from a neighbour with 2024/25 data — now judged per school on
its own latest year. (2) The '~N disadvantaged pupils' cohort multiplied
eligible_pupils and disadvantaged_pct resolved independently across years
— now both come from the same yearly row that supplies the displayed
percentage.

S1: first-choice chip banded (More than half / About 1 in 3 / Over 1 in 4
missed out) so a 44%-offered grammar isn't understated by half.
S2: Progress 8 explains its absence for 2024/25+ cohorts (no KS2 baseline,
COVID) instead of a bare 'No data'.
S3: KS4 trend charts get their own honest gap caption (2019/20-2020/21
unpublished; later years not in our dataset yet); y-axis 'Value'→'Score';
buildCompareChart exposes englandOnlyYears.
S4: all-through schools labelled in chips, rail caption says 'N schools ·
<phase> view' for mixed baskets, whole-school roll no longer judged
against the single-phase median, community section carries an all-ages
caveat.
S6 (spec §8.5): disadvantaged attainment shows the cohort behind it
('of ~50 disadvantaged pupils').
