school_compare

The compare chart squashed clustered schools into a thin band (y pinned
0-100) under an in-chart title + per-school legend that ate ~40% of a
300px card, leaving converging lines indistinguishable on phones.

- Auto-fit the y-axis to the data on all viewports (computeYBounds in
  lib/utils: padded + min-span for percentages, symmetric around 0 for
  progress, fitted for scores; negative pct-named trend metrics are not
  zero-clamped).
- Distinct point style per school (circle/triangle/rect/rectRot/star)
  as secondary encoding for convergence and colour-blindness.
- Mobile: drop in-chart title/legend/axis titles; add a chip row (colour
  dot + name) that doubles as tap-to-focus — highlights one school's
  line and dims the rest. Chart card 300px -> 340px, nearly all plot.
- Fix a latent colour mismatch: datasets were built from Object.entries
  whose integer-like URN keys enumerate in ascending numeric order,
  desyncing line colours from card colours; the chart now receives the
  ordered school list.
- Union years across schools instead of taking the first school's.
- Extract PerformanceChart's matchMedia pattern into hooks/useIsMobile.

Unit tests for metricKind/computeYBounds; e2e journey covers the mobile
chips and focus toggle.
